    Firefox Multi-Account contains are awesome for software development and testing! At my work we usually work at tools which have three roles: user, reviewer, administrator so I generally have three containers for these user accounts. This means I can be logged in with all the accounts I need for testing in the same web browser without resorting to private mode (which does not remember cookies between sessions anyway).

    In addition, I use the temporary container add-on[0] which also uses containers, but throws them away after being used (like reference counting).

    These two tools have seriously improved my ability to both develop and test applications without the hassle of logging out and logging in all the time or needing any tricks when needing multiple clean browsing sessions.

      A few more usecases that I've added to my workflow since discovering container tabs:

      * Work/personal separation

      * Multiple AWS accounts

      Also, I am very impressed with how well they're integrated into Firefox. For example, opening a link in a new tab will preserve the container. CMD+Shift+T will restore a recently closed tab and remember its original container. I really like the color coding too.

        Here is my use case.

        * Work/Personal * Multiple AWS Accounts * Bank * Facebook (https://www.mozilla.org/en-US/firefox/facebookcontainer/) * Shopping * temp (test, disposable )

        The only time I use private windows is when there is a glitch.

          Use a different Firefox profile for work/personal.

          Sign-in to personal (while at work) to sync bookmarks if firewall allows. Depending on whether you trust your employer you could sync further personal settings.

          Don't sign-in to work profile and no work bookmarks or settings/logins get shared.

          Don't get me wrong: multi-account containers are a blessing for those rare days when you absolutely have to log-in to facebook.

            What are the differences between a profile and an account?

            • anonfwd7 171 days ago

              I suspect the mapping between accounts and profiles is 1:1, but you can have a different profile which is not associated with an account.

            I think the reason why it is so well integrated is that it used to be part of the standard installation of firefox and only later moved into an addon.

            • markosaric 172 days ago

              Containers actually still are integrated in the standard installation of Firefox and can be used even without an addon. You just need to turn them on in about:config:

              privacy.userContext.enabled to true

              privacy.userContext.ui.enabled to true

              privacy.userContext.longPressBehavior to 2

              I love using containers with privacy.firstparty.isolate set to true too for extra protection.

                This add-on is a GUI to the underlying mechanism. They even say you can choose to use the non-GUI lower level hooks. They think this GUI is a nicer user experience

                  Thanks a lot for this.

                  I never understand why Mozilla doesn't allow to enable this in the settings.

              Sounds like I need to move some of my devtesting back to FF. The ability to open a new session with a fresh disconnected session (so no shared session cookies) is one of the few things I miss from bad-old-IE (as simple as "File|NewSession"). Very useful, as you say, for testing workflows between different users.

              Of course you've always been able to setup multiple profiles for FF, but that is setup that I was usually too lazy for given it could be done ad-hoc in IE.

              • greggyb 172 days ago

                I have to agree with you on temporary containers. I spend most of my time in temporary containers. I trade the annoyance of having cookie popups literally every time I visit a page for not actually having to worry about the impact of those cookies.

                I have it configured such that middle-click opens links in new containers, and left-click opens in the current container.

                • NoMoreBro 172 days ago

                  For annoying cookies popups you can try this https://addons.mozilla.org/it/firefox/addon/i-dont-care-abou...

                • pmontra 171 days ago

                  I also use containers.

                  Hide the popups with uBlock Origin. You pick the element with an inspector like tool and they are gone forever. Also use Cookie Autodelete to remove any information they attach to your browser.

                  If you really care about a site, make your choices in the cookie popup and grey/white list it in Cookie Autodelete.

                    > for not actually having to worry about the impact of those cookies

                    I'm using a plugin called Cookie Autodelete for this and like it

                  • prions 172 days ago

                    Same! I have three (dev, stg, prd) aws accounts. Without containers, I'd need to log in and out to jump between s3/emr/etc buckets between environments. With firefox containers I can run all three concurrently.

                    • srcmap 172 days ago

                      One can do that with ff profile, right?

                      Is the only different between this containers vs profile the container is tab base vs profile will be different windows?

                      • O1111OOO 170 days ago

                        I've opted for profiles. With profiles, it's like getting a completely new browser. You start off with the default about:config, preferences and no extensions.

                        The way my main FF browser is set up, I have multiple privacy enhancing extensions (including uMatrix), highly modified config, tightening of privacy preferences, WebRTC off, service workers disabled, telemetry disabled, etc and etc... This can create some problems on sites that pour hundreds of millions into tracking, data-collection.

                        So I have additional profiles that are Amazon-specific, Google-specific. If I facebook'd, I'd have a profile for them too. Each of these domain-based profiles are far more liberal (minimal extensions and such; fewer config tweaks). I even have a profile that's 100% Private Mode (ie, history, cookies... deleted after shutdown) with it's own set of config tweaks and extensions.

                        I use my privacy-enhanced default FF for most sites w/o issues. I wanted Google and Amazon completely separate while providing them more access to my browser (so that I could enjoy the full web experience without worry that a browser issue would make it easy for them to steal my entire browser usage). So they're free to rummage around, read cookies, access APIs - but they're only getting their own stuff back.

                        I feel profiles provide a better defense (all settings, cookies, storage in their own subDirectory) and much more flexibility than containers.

                        • JaggedJax 172 days ago

                          Functionality is similar, but containers are a lot easier to manage than profiles in FF for me. Everything is right in the container icon and you don't have to re-login like when setting up profiles. You can create new containers and remove unused ones in a couple of seconds vs profiles which are much slower to manage.

                          I don't bother with profiles any more, especially since there's a one click option to open all the container tabs in a new window as well.

                          The huge downside with them is they don't sync across devices. If/When this comes they will be perfect.

                          • NoMoreBro 171 days ago

                            Containers share the same set of extensions and settings, profiles don't.

                        • Vinnl 171 days ago

                          Having every new tab open in a temporary container was a bit jarring for me (it closes the new tab right after opening it, then opens it again in a temporary container tab), but what works very well for me is the ability to open specific links in a temporary container using the Trash Panda extension: https://addons.mozilla.org/en-US/firefox/addon/trash-bear/

                          • pletnes 172 days ago

                            Seconded. We have several levels of dev/test/production cloud services, including backends on cloud providers etc. It’s great to have one container for each group of services!

                            • captaincole 172 days ago

                              Agreed and seconded. I use them mainly for testing and for demo. If I need to switch personas but not have multiple private tabs open it is a game changer.

                              • ssklash 172 days ago

                                Thanks for this tip. It will come in super useful during web app penetration tests, being able to have sessions with multiple users open at the same time.

                                • Maximus9000 172 days ago

                                  Wow, thanks for that tip! That's an awesome use case for this addon.

                                • no_protocol 172 days ago

                                  I can forgive the somewhat limited user interface for setting these up that is in the stock add-on, but the lack of automatic syncing of rules to all computers with the same Firefox account is really frustrating to deal with.

                                  Putting in the effort to get them all set up nicely and then having them either blown away (I think this happened once...) or needing to get that over to another computer has made me limit my use to fewer containers than I probably would otherwise use.

                                  • alyandon 172 days ago

                                    That particular bug (having my container setup get blown away) has happened to me several times along with other bugs like not properly restoring tabs in the designated container when you restart FF to apply an update.

                                    Bugs like that would be forgivable if they'd at least provide a way to export/import setups.

                                    • briffle 172 days ago

                                      There is a plugin that will sync the actual containers, but it doesn't sync your rules you setup to always open site X in your personal container, etc.

                                      Without that, its useless to me. There is a bugzilla [0] for it, and 3 years ago, it was said they were going to look more into it, and nothing really since.. Its frustrating.

                                        M-A-C dev here ...

                                        We're actually pretty deep into the work of adding sync to M-A-C. https://github.com/mozilla/multi-account-containers/pull/161...

                                        Predictably, synchronizing data is complicated, so it's taking a while and we're trying to do it in a way that doesn't destroy any existing data. So we'll be doing some heavy internal testing on it before we release it.

                                        But it's definitely coming.

                                          I was all set to try this, over the syncing in Chrome of different Google accounts. Ah, well, when they get them syncing I will try it.

                                          I love Firefox Multi-Account containers!

                                          My only complaint (and really this is my biggest gripe with Firefox in general) is that there is no support for syncing containers using your Firefox account. This means every time I set up a new computer I have to reconfigure my containers and for each computer I have to re-associate all the sites I have sandbox with their own containers. This is such a huge pain.

                                          Other than that, I love it.

                                            It's also a great issue for me since I have to reconfigure everything.

                                            I don't know how the Firefox account works but the fact that FMAC is an extension and not natively included in Firefox may be explaining why it's not synced ?

                                              Pair it with "containerise" (https://addons.mozilla.org/en-US/firefox/addon/containerise/ ). With containerise, you can easily edit a text file (host, container name) to create/edit/backup multiple containers.

                                                I was hoping somebody would share the news about this addon and I'm glad that I wasn't disappointed!

                                                  Does it sync this across multiple machines? Can I export/import this list?

                                                  • babak_ap 171 days ago

                                                    Unfortunately, it doesn't sync. You can copy the text anywhere (e.g. email to yourself!) and use it elsewhere; it's still a much better UX compared to the built-in functionality.

                                                  • CivBase 172 days ago

                                                    I really really want support for multiple browser profiles in Firefox. Multi-Account Containers are cool, but they don't allow me to change my bookmarks or browser extensions. This is the only thing left Chrome has over Firefox that I honestly care about.

                                                    The profile manager (about:profiles) comes so close, but it's just not as elegant as Chrome. Starting Firefox with the profile manager also causes issues when the OS tries to open another Firefox instance.

                                                    They have a Firefox sync profile badge now. Just give me the option in that menu to open a new Firefox instance with another profile. And when the OS tries to open a webpage, just use the default profile - or even whatever profile I opened a page with last.

                                                    • Someone1234 172 days ago

                                                      Every time this comes up, everyone always dismisses it by just pointing to about:profile or the launch flags, but in my opinion those are weak excuses.

                                                      Chrome made profiles a first class citizen and they're an absolute pleasure to use. I literally use them every day. Firefox having a bunch of buried half baked UI isn't really an answer to that.

                                                      I believe Firefox is a better browser overall. Only this (profiles), the terrible bookmark/history experience (wtf is that?), and the developer bar are the remaining weaknesses.

                                                      • lovebigmacs 172 days ago

                                                        The entire Library, Bookmarks/History/the archaic Downloads popup, all just makes me immensely sad. Meanwhile I keep seeing more badges (Pocket, Screenshots, Lockwise, etc) crap popping up in the browser UX...

                                                        To add on to what you're pointing out -- they even cloned Chrome's "profile-icon-in-the-bar" model, but didn't actually give you the ability to switch profiles with it! Instead more places to shove more links that I forgot about - Firefox Monitor and Firefox Send.

                                                        • anonymousab 172 days ago

                                                          The history and bookmark management also has some unfortunate performance issues. I'm fairly certain there's a memory leak or something as well, as deleting several thousand entries at once (say, via 'forget this site' menu options) effectively breaks the browser until restart even when it has finished the operation.

                                                          A comment in the bugzilla for this issue[1] seems to suggest that they'd like to rewrite History at the very least. So it's on the priority list somewhere.

                                                            "Forget this site" seems to work well for me, but selecting thousands of history items manually and then pressing the delete key will lock firefox up for tens of minutes.

                                                            There is definitely something profoundly broken with how history is being handled. Probably more than one thing that's broken, from the sounds of it.

                                                          Firefox's bookmark is superior at the core (the most important to me is that it supports tags) IMO, but yeah, the UI and UX is pretty bad.

                                                            Not only that, but attempting to actually create a lunch shortcut on MacOS or Linux with custom profile is quite an exercise since it's not as intuitive to do as on Windows.

                                                            It would also be a great place to advertise the Containers extension for those users for whom profiles are a bit overkill (especially them opening in different windows).

                                                            I made a fork of this that gives you some additional control over how links are treated - specifically, you can set it up different rules for what container to open a page in depending on what container it was opened from: https://addons.mozilla.org/en-US/firefox/addon/containers-wi...

                                                            The rationale is that you rarely want pages that you open from random Facebook posts or Reddit submissions, or pages that you arrive at by following more links from those, to have access to your Facebook or Reddit login information.

                                                              This seems really similar to the Facebook container (made by Mozilla, https://addons.mozilla.org/en-US/firefox/addon/facebook-cont...) and the Google container (a fork of the previous, https://addons.mozilla.org/en-US/firefox/addon/google-contai...)

                                                              The annoying thing about your extension is that the end-user would need to know about and update the domains they want to keep isolated. It would be great if all these extensions/features were built into the original extension and there were updating isolation lists similar to the uBlock Origin lists (EasyList, Peter Lowe's list, etc.).

                                                              • JaRail 172 days ago

                                                                I use Temporary Containers (https://addons.mozilla.org/en-US/firefox/addon/temporary-con...) to do this. You can customize how you want links handled when they target different domains. It takes some getting used to as there are a handful of options to understand/customize. Plus you can have customizations where you're replacing the current container with a new one which kills off your back button history. Just need to be aware of the quirks. It's definitely still in the realm of power-user UX.

                                                                • Krasnol 172 days ago

                                                                  Thank you.

                                                                    I'll be trying this— I like Firefox containers a lot, but I dislike how session-oriented they are. You can force a particular site into container X, but every click from there will stay in container X unless another rule forces it to a different containers.

                                                                    What I want is something more like "jail site X in container X, and open every non-X link in a temporary container / container Y / whatever."

                                                                    • pedantsamaritan 172 days ago

Anything opened from HN will stay in the HN container and non-HN sites get cookies deleted shortly. This reduces some tracking for me, but doesn't do anything for something like an XSS against HN that the GP seems to be referring to.

                                                                      [0]: https://addons.mozilla.org/en-US/firefox/addon/cookie-autode...

Submitted the extension to the Firefox extend contest but not even a mention there. You can check an old video [1]

                                                                      [1] https://www.youtube.com/watch?v=2Pfg-kJ4nAw&fmt=18

I have an elaborate and carefully crafted set of containers. I even have one for TheGuradian where I am allowing ads but the moment a new machine is added to the workflow all is lost.

                                                                        • dddddaviddddd 172 days ago

                                                                          https://www.ctrl.blog/entry/firefox-fpi.html

This is fantastic not only for privacy/security for everyday use but also great for testing sites while doing development. It becomes really easy to be logged into all the different types of users in a website at the same time and see the interaction.

                                                                              • romaaeterna 172 days ago

My default browsing experience is that most pages have never seen my computer before (at least as far as cookies go), and don't get to set anything that will stick around, unless I manually add them to a named container.

                                                                            • milofeynman 172 days ago

And broke stuff randomly on my home PC. The biggest problem is that you can't easily add a whitelist to fix it. At least you couldn't back when it first came out.

                                                                              • k__ 172 days ago

                                                                                Also, it didn't work on mobile.

This means that if anything reset your Firefox profile (like that bug they had last year) or if you use multiple computers, you'll be spending a lot of time duplicating the configuration:

                                                                                    Without a built-in sync feature, I continue to use the simplest form of cookie management: Private Windows.

(Actually adding it into the bookmarks and syncing across devices is a pain, but not as painful as not being able to open up bookmarks into specific containers).

My only annoyance with it is that One Tab -- www.one-tab.com -- doesn't remember in which container to re-open saved tabs. I really wish this feature would be implemented in Safari, Edge, and Chrome.

                                                                                            • dmachop 172 days ago

                                                                                              This was long time ago. It does compartmentalize the browsing info but the history is still accessible with other containers. For example, a Shopping container should have its own history. (https://github.com/mozilla/multi-account-containers/issues/4...)

                                                                                              • rozab 172 days ago

                                                                                                If I wanted to completely separate things like this I would use multiple different profiles. The advantage of the extension is that your history, settings, etc remains constant across the containers.

                                                                                                • anonymousab 172 days ago

                                                                                                  Profiles are unfortunately much more cumbersome to use than in Chrome.

                                                                                                  The UX that container tabs have - being able to use them in the same Windows as other tabs, with accessible open-in options from the tab bar and from various context menus; creating new containers as easily as specifying a name and no more - is the UX that I wish Firefox had for their profiles.

                                                                                              • rsync 172 days ago

                                                                                                I am very excited about this feature and have tried to incorporate it into my workflow but find it very difficult.

                                                                                                I want to open a window (not tab) as a particular profile, and then all subsequent tabs in that window are of that same profile.

                                                                                                This would seem to be the basic, beginning use-case from which all other use-cases would follow. I don't know why it doesn't exist ...

                                                                                                • freddie_mercury 172 days ago

                                                                                                  • rsync 171 days ago

                                                                                                    As far as I can tell, the only way to open a specific container tab is to mousey-mouse-mouse to:

                                                                                                    File > New Container Tab > Blah

                                                                                                    Of course that use-case should be preserved, but it's woefully inefficient ... if you have a profile you do a lot of things under, you'd create a window and then (keystroke) (CMD)-t to get a new tab ...

                                                                                                    • Vinnl 171 days ago

                                                                                                      It's not super-efficient, but it is keyboard accessible: press Ctrl+. to open the Container selection menu, then the down arrow to the Container you want, and Enter to open a new tab in that Container.

                                                                                                      • rsync 170 days ago

                                                                                                        So, you don't need to down-arrow and pick, you can just:

                                                                                                        ctrl + . (ctrl + period)

                                                                                                        then hit '1' or '2' ...

                                                                                                        I type in a URL and Firefox knows which container to open it in already.

                                                                                                        I've been using Firefox with containers since it came out and I've never wanted to do that.

                                                                                                          • _nedR 172 days ago

                                                                                                            You can judge for yourself by typing 'firefox -P -no-remote'. Right there, having to use the terminal , has already made it more clunkier than Chromium's solution. Admittedly, Firefox profiles are clunkier to launch & manage - like a hidden feature that has rebuffed all my attempts to streamline their management, as if by design. This can be remedied by use of desktop shortcuts (You can create separate shortcuts for different profiles) but then you have to also deal with the idiosyncrasies of your Desktop Environment (Gnome in my case :/) .

                                                                                                            Once its launched its pretty much like running to separate firefox instances in your system with separate bookmarks, histories, settings, addons - like in Chrome. So it is a lot more heavier than containers as a result. Which is why i think the 2 functionalities shouldn't me unified like people in the comments seem to be asking. Similar to Threads vs processes. We need both.

                                                                                                            • baggy_trough 171 days ago

Firefox containers aren't profiles and imo shouldn't replace them. They should make profiles more user-accessible, but both solutions should exist simultaneously. If anything, effective use of containers requires more advanced knowledge & awareness making it more suitaed for advanced users.

So when the browser opens, there's usually nothing in it, and then the signing for the site I want to go to is auto filled making login pretty simple, then I quit on close.

                                                                                                        That's the best I've been able to do so far.

Otherwise it's basically a fancy "private browsing" window.

                                                                                                        What you can do is have a certain site auto open in a specific container, that way you can just go to the site from a bookmark, link, the address bar etc and it is just one step, but this breaks when you have more than one account on the same site and want a container for each.

                                                                                                        If anyone does know a workaround for this, or knows if there's a fix coming, would be really interested to hear!

                                                                                                          A couple of caveats, though:

                                                                                                          * If you disable Multi-Account Containers at ANY TIME, all of your configuration will be gone. So, don't ever disable it. Or just be prepared.

                                                                                                          * They don't sync with Firefox Sync.

                                                                                                          * I use Alfred and in some of my workflows, when I have URLs that are designed to always open in a particular container, FF just won't open the URL. /shrug

                                                                                                          * Always opening URLs depends on the URL. This works great for apps which give you account-specific URLs (e.g. Harvest, Jira, other services...) but doesn't work at all for stuff like Gmail or Drive. I wish there was a way to get FF to ask you how you want to open a URL like that.

                                                                                                          • lovebigmacs 172 days ago

                                                                                                            I would happily donate a thousand dollars towards seeing MAC integrated as a first-rate feature. As-is, I have a massive love-hate relationship with it.

                                                                                                            1. I'm horrified using Chrome these days. Browsing to a random site and having my Google account avatar pop up and offer to log me in is really unacceptable. So I fundamentally love what MAC provides. (Though some of this is also Firefox's aggressive cookie options.)

                                                                                                            2. It's ridiculously buggy. "Reopen in Container Tab" often reloads in the exact same container. Trust me, I've checked the various bits of configuration that control defaulting certain domains to certain containers, there are just times that it does the wrong thing.

                                                                                                            3. The config is hard to backup? I gave up last time I tried. It's a lot of work to get all of the domains setup to open in certain containers, establish the naming/coloring conventions so that it's not a mental burden.... and then have to lose it when I'm inevitably told that somehow Linux performance will be magically better if I make a new profile.

                                                                                                            Example usages: multiple "personas". I have a Google Suite account and domain for certain things. I don't have issues switching between Google accounts because to Google, I'm only ever logged into one at a time. Dev/Test purposes.

                                                                                                            • dang 172 days ago

                                                                                                                I recently started using the multi-account container addon. And I love it. Just before I also started using Mozilla's Facebook container[1] and it works as intended as well.

                                                                                                                I know supercookies and other fingerprinting means I am probably being tracked still, but at least I am minimising it without going full time incognito.

                                                                                                                Previously I was using Profiles to separate personal, work and clients, and though about:profiles help switching quicker it was still messy, and confusing which profile a link would open in etc.

                                                                                                                Now I can separate Facebook, Google products and Amazon into their own containers. I can keep various client browsing separate from my personal, I can keep more suspect websites in its own container, finance, infrastructure etc. Love it.

                                                                                                                * [1] https://addons.mozilla.org/en-GB/firefox/addon/facebook-cont...

                                                                                                                  I use this and for the most part it works just fine. The other day I ran into a problem where it got into this loop and I ended up making Chrome as my default browser just to get around this issue.

                                                                                                                  The issue is when you've an app that needs Google authentication and it opens the browser. To be more specific, I was trying to log in on Postman using the web authentication option. It opened my default browser (Firefox) just fine but it opened my other container (Work) which is not associated with my Google login. When i asked it to re-open the page in the other container (Personal), it lost all the redirect information and wouldn't let me continue back to Postman. I swear I had this same issue with another app but can't recall its name.

                                                                                                                  I suppose i could workaround this issue by having my personal container handle all the postman links but it seems like too many steps to get one thing.

                                                                                                                  • sleavey 172 days ago

                                                                                                                    Does it work with Firefox Sync yet? That's the only thing stopping me from using containers - I've got multiple machines I would need to sync containers between. Last time I checked (admittedly a few years ago) it didn't and it seemed unlikely to be added any time soon.

                                                                                                                    • lukewrites 172 days ago

                                                                                                                        I combine containers with running multiple copies of Firefox under different profiles. I've been using multiple profiles for years, and I think it still offers some advantages even with container support. The big one is that one instance of the browser can crash or be restarted without any impact to the others. It also distributes resource consumption over multiple independent processes, though I'm sure there's some overhead in this approach. Finally, it allows slightly different settings for each profile depending on need. I manage common settings with a user.js file.

                                                                                                                        One profile is for logging into various services I regularly use, one is dedicated to day-to-day surfing, one is for local development (there are no addons in this one), one is specifically for webmail, and one is specifically for Trello. Containers are most useful with the first two profiles...especially the first, so that the various services have some level of isolation.

                                                                                                                        EDIT: details, typos, etc

                                                                                                                              I might add separate containers for separate Twitter accounts, because the multiple account UI on Twitter's web site is atrocious, IMO. I'm constantly "in the wrong account".

                                                                                                                              At work I set up a container for all the domains and servers my company uses versus everything else.

                                                                                                                                  Unfortunately at work we are using a lot of OAuth, so I am supposed to use AWS and others with Google authentication. Which means that I cannot isolate them anymore. At the moment I still use my old AWS IAM account, but the plan is to remove the credentials. On other services I have never had any separate credentials :(

                                                                                                                                  • screaminghawk 172 days ago

                                                                                                                                    My key use of this is to manage multiple login sessions to the same site. Having a bunch of spare containers lets me do this in the same browser window. And I don't have to worry about closing them (compared to using private browsing)

                                                                                                                                  • tomashubelbauer 172 days ago

                                                                                                                                    The simplicity of these Containers really amazes me.

Add in Conex (https://addons.mozilla.org/en-US/firefox/addon/conex/) and you have really great tab group switching WITH containerization / "firewall" between containers.

                                                                                                                                      You can't get anywhere near this with Chrome as far as I'm aware.

Containers are incredibly lightweight compared to opening a separate profile. I would say Firefox profiles are more cumbersome to use than chromes..

Similar to the "facebook container" or being able to have multiple aws account sub-containers in my "work" profile. It's something I wish I could do.

Since you can switch without having to log off, it's really convenient. I understand partners sharing accounts and such but it's really just a better workflow/experience IMHO.

It's necessary to add accounts.google.com and mail.google.com

                                                                                                                                                  I think I can't isolate Google search to ours own container.

                                                                                                                                                  I'm also using strict setting and cookies are cleared when Firefox is closed, and Gmail and accounts domain are white listed.

                                                                                                                                                  The UI of this addon could be a little better.

I don't. So I have 2 Google containers (work + private) where I am logged in for Gmail, Drive etc. But search, maps, etc. I do in a 3rd container. Yeah, you cannot blindly follow all links, but that doesn't bother me too much.

                                                                                                                                                    • jokoon 171 days ago

One of the logging platforms we use (PaperTrail) uses a single cookie for connecting to their platform. This in turn, makes it a complete pain if I want to view logs for a dev/staging instance because it logs me out of our live logs.

                                                                                                                                                    Multi-Account Containers completely fixed this for me.

If you want temp profiles you can write a script that: - copies a good initial profile to /dev/shm - launches Firefox in firejail with —private that points to the dir - delete the dir

                                                                                                                                                      If you want the containers to stick around you can avoid /dev/shm and keep the dirs around instead.

                                                                                                                                                                These are pretty good, but the Chrome implementation is better. Specific complaints: - can't tie a bookmark to a container. - too many clicks to open a new tab in a container (in Chrome the whole window stays tied to the container, not just the tab) - bookmarks and history aren't container-scoped.

                                                                                                                                                                • _nedR 172 days ago

                                                                                                                                                                  Are you referring to Chrome's profiles? Because Firefox's counterpart to that is Firefox profiles, not containers. Firefox profiles are clunkier to launch & use though (like a hidden feature that has rebuffed all my attempts to streamline their management, as if by design). Type 'firefox -P -no-remote' to start with firefox profiles.

                                                                                                                                                                  IMO containers and profile functionalities shouldn't be mixed. Containers are a lightweight version of Profiles. Running 2 profiles is essentially running 2 separate browsers running with separate histories, add-ons, bookmarks, settings. A bit like threads vs processes.

                                                                                                                                                                  • dralley 172 days ago

The whole point of this feature is that you can have all of the cookies and persistent storage of a tab or set of tabs sandboxed, without affecting your actual browser history or bookmarks.

                                                                                                                                                                    If you want that, use profiles.

There's even extensions like "temporary container tab" that will give you a fresh container with one click.

                                                                                                                                                                    • baggy_trough 172 days ago

Chrome "personas" seem to be much like Firefox containers, but somewhat easier to use. Don't Firefox profiles require restarting the browser?

                                                                                                                                                                      I guess I am not smart enough to figure out the simple configuration you mention.

It's extra work to install it, and the fact that it's an extension probably means that it's not tested as well as normal browser UI. I really hate using extensions because I like to keep my software plain vanilla as possible to avoid strange bugs.

                                                                                                                                                                            • dralley 172 days ago

If you aren't aware of what it is and managed to accidentally activate it, you'd probably get really confused why you had to keep logging back into facebook.

                                                                                                                                                                          • znpy 171 days ago

                                                                                                                                                                            I still think that firefox profiles are better.

Setting these up on all the devices is a pain!
