Hey there! I'm one of the devs on this project. We made some progress last year on per-container proxy support. Follow this issue for (hopefully soon) progress here:
https://github.com/mozilla/multi-account-containers/pull/190...

Probably not exactly what you want but for proxies you can use Container proxy[0] (not affiliated), which allows you to assign different proxies added by yourself to specific containers.

I've used containers with container proxy for well over a year and it works great for segregating work traffic on my home system. I use a container for work traffic that is assigned to an SSH session to my work system that exposes a SOCKS proxy that I make sure is running.
Eventually I moved work browsing to a different browser that I set to run through that proxy explicitly, but I still have the Firefox config set up in case I don't want to launch that, or don't care to copy and paste to the work browser some times (I wish I could find a way to make links launched from Outlook/Teams to open in Chrome but other links to open in Firefox).

If you are on a Mac, have a look at finicky to manage which URLs should open in a specific browser.

I'm not, but just yesterday or the day before I was thinking maybe I'd write a simple application to take the URL and make decisions what to do with it afterwards based on whatever data I decide is relevant (time of day, domain, etc). If I had access to what the source application was that would be ideal, but I doubt Windows 10 supplies that.

Congrats, you just invented the Tor browser. Or at least a variant where you are happy to store history etc on your machine.

Does Tor have enough bandwidth for streaming now?
On the rare occasion that you can get Youtube (because of google's rate limits) or similar to open on Tor, it can easily stream HD videos.
You can use profiles for von stuff. Containers only really works for site based state.
If you care about security through compartmentalization that much, you should try Qubes OS. It allows to use different VPNs for different VMs with a pretty good UI.
Use FoxyProxy in conjunction with containers.
The real gem is this extension: Temporary Containers
https://addons.mozilla.org/en-US/firefox/addon/temporary-con...
Basically every new tab is a new temporary container. Isolation all the time, by default. It's an added exercise for the reader, but you have to go into the settings of the extension and modify some of the mouse behavior. Basically if I want a link I click to share the same container as the parent, I Ctrl + Click. Left-clicking or middle-clicking is always a new temporary container.
Containers are so much more than cookie isolation.

I add Containerize to that:

It lets you define rules for URLs to allow any URL matching a pattern to always open in a certain container.

How is this different than managing the site list for a Firefox Container? Just that it's a CSV and patterns are supported?
Do you just not define anything in the Firefox Container site list, and rely on this to manage it instead?

The main Firefox Containers extension has a nicer UI but quite a lot of missing features. Mainly the ability to edit the site list directly, and the fact that the way it registers a site against a container means it can't support adding a redirect to a container, nor (related) having separate Google services in separate containers (e.g. a Youtube container and separate Gmail container).
For me a source of some frustration is redirects and subdomains, which I need to visit manually with network switched off in order to add to the right container. This will help a lot for that issue!

I tried using this but it doesn't preserve case so the regex matches don't work..
Doesn't seem to be very active either
I eventually moved to one of the fields that fixes the issue but have to install that from xpi

I use this as well and it's quite good.
The only thing I sometimes have a problem with is when going through a payment flow using PayPal and forgetting to open the site in a persistent container. Many sites will fail to process the payment on the redirect back to the site as it ends up in another container.
I haven't looked recently, but I didn't see an option to open a site in an existing temporary container based on domain if there is one already open which I believe would solve this.

Agreed, I love this. Just use a different hot-key to open a new tab that is in its own container.
How is that different from anonymous browsing tabs?
Anon browsing allows max 2 separate simultaneous contexts: the anon session and your tracked session. This allows many different anon sessions. It's also a nicer more consistent integration if you already use (permanent) containers.
That makes sense! Thanks for the info!
Will containers save your session when you close them and reopen them again later?
Will containers save your session when you close them and reopen them again later?
That's configurable. Sessions can be permanent, can be deleted as soon as they're closed, or a set period of time after last use.
It's per tab not per window and they can coexist with trusted containers. It also has a non-automatic mode where you select sites that open in temporary containers instead of selecting sites that don't.
Thank you for the info! That's really cool.
Sounds almost like you can have containers like profiles.
Where one tab is opened in a container signed in to an account and another signed into a different account.

Apart from the features in the sibling comment, your history will be kept.
As well as cookies between restarts, so eg. you don’t have to login to google inside your google container.
If you can close containers and restart/reopen the container tab and have all of the session information still saved in that container...
That means you can almost implement google profiles with containers.
Except it's kinda per tab instead of per window.
And that's really cool.
Am I conceptualizing that right?

Firefox Containers is a great feature that deserves more credits. This feature allows us to avoid tracking, while at the same time ensuring the convenience of use and does not require the user to change their habits. Do you want to limit facebook? Create the container, set the default facebook.com opening in it, and use the browser as before. This should be a standard feature in any browser.
Not a container user so I hope you don't mind me asking, how is this different to opening facebook in new private tab/window? Is the convenience in the act of automatically opening it in container if you type in facebook.com or follow a link to it?
what you mention is one advantage, another example is that you are not limited to 2 contexts (private tab & non-private tab vs as many containers as you need).
Related to the advantage you mention is also the reverse: clicking a non-facebook link from the facebook container can (if you want) open a non-facebook container

Ok starting to understand it. Seems like something I would have a hard time explaining to a non-tech person.
yes, you could describe that use case as "quarantining" websites in short, but I'd say it's a power user feature if managed manually.
If you install the "facebook container" extension, it's zero conf but it's only for facebook.
Another use case I saw users being interested in, is you have 2 (or more) accounts on a website and you can login in both at the same time in 2 separate containers (you cannot quarantine the website to the container in this use case because you need to open it in multiple containers). You can do that with incognito, but the second one is very temporary as closing the browser is going to log you out.

Love seeing mentions of Firefox containers on HN. The native multi-account containers UI isn't able to do things such as container filtering, bulk rename/delete/recollection/etc, so a bit less than a year ago I wrote a lightweight extension to help manage containers here:
https://addons.mozilla.org/en-US/firefox/addon/containers-he...
https://addons.mozilla.org/en-US/firefox/addon/containers-he...
I'm not sure how to edit my original comment, but "recollection" should be "re-color". This was due to autocorrect.
Bookmarked. Will try immediately upon arrival at work.
Containers are great! But since the recent v.91 update screwed the tabs up so much, there's no quick visual way to scan and see which container-type each tab is.
Great stuff, well done Mozilla! What's the point in being able to customise a container's appearance, including colour, if they're not described on the tab itself?

TreeStyleTabs...
next to Containers, it is the only reason I still use FF, if FF drops support for either TreeStyleTabs or Containers there will be zero reason for me to continue using it.

Sideberry is TST with better perfomance, FYI.
Also, right there with ya - treed tabs is the only reason I stick with FF.

Better performance not necessarily, but you can set custom rules for containers. You can set the user agent and proxy settings on a container base which is nice
Firefox used to freeze up periodically when I used TST, and that went away when I switched. That's all I meant.
Yup went away from TST for the same reason.
Made a performance comparison a few weeks ago to compare sidebery with TST (I got a few thousand open tabs, spread over ~50 windows) and didn't get the perfomance penalty I used to.
Side note: some plugins "crashed" when testing TST, sidebery and tab stash at the same time. Sidebery seemed to be the most stable. (had at one time no adblock anymore so that's something)
Side note 2: I really like some things about sidebery for instance the grouping of tabs and the possibility to see your bookmarks. TST needs to be extended through plugins for this, but some functionality is really only available in certain plugins.
Side note 3: The tab handling of sidebery and TST feels quite different... If you are used to the normal tab handling you will be confused with sidebery... a lot (you can reconfigure it to be more vanilla, but I had multiple problems configuring the plugins). The tab switching isn't at all obvious at times.
All in all I would recommend everyone to play around with containers and vertical tabs :) I know this little rant here went on a huge tangent from the article, but I wanted to clarify my experience with the named plugins.

How do I get over the reluctance to grant an extension to "Access your data for all websites"? I would love to have some of these extensions but it feels like a huge security risk.
If you really want an extension that requires that, and if it has a repo, you could vet the code a bit (it's JavaScript, so somewhat accessible), and load it as an extension from a file after packaging it up.
Alternatively, you can install it, look in your profile dir until you find that extension, and look through all the code it's using, and turn off automatically update extensions in Firefox when you're happy you want to keep it.
People can say what they will about the great extension convergence where Firefox switched to Chrome style extensions, but having everything just be JavaScript that you can easily review yourself is pretty nice.

By reading the feature set and realising that some of them cannot work without that permission. For example, you can't have a password manager, a CSS style injector, or an ad-blocker without that access.
After taking a quick look at the add-on from the comment above, I bet it's the snapshots feature that requires it.

If you previously disabled the Proton redesign in about:config then you need to undo that setting. It no longer disables Proton, but it does interfere with the colored line that indicates which container each tab is a part of.
i think tweaking browser.proton in about:config will break this. Saw this on Reddit a while back when looking at why my containers were bugged (for a totally different reason.
I use 'Container Tabs Sidebar' [0] add-on which gives me a tree-style view of the different pages opened in their corresponding containers.

You might need to get your vision checked. Each tab in a container gets a colored top border. And it's sizeable.
Your decision to be a dismissive smartarse really annoyed me, because of course i'm not that much of an idiot.
Turns out that like another respondent here, animesh, I had 'browser.proton.enabled' set to false too from an attempt to fix my tabs last time FF buggered around with things. Setting that to TRUE has got the colours on.
So, only slightly an idiot...

When I see anecdotes like this, I better understand why Mozilla is moving away from about:config. A thousand variables makes issues far more difficult to debug.
True, but I'd never have fritzed with the settings in the first place if Mozilla had allowed me to easily keep things as they were / customise things.
How do you resize the colored top border?
I don't believe this is exposed by default, but playing around with userChrome.css should be able to change it.
Yes, I’d love to make the colours big and bold. No more mixing dev and production…
Not anymore. Please check again. I don't see the colored top border on container tabs. I'm on FF 91.0.2 on Win 10.
Works on both 91.0 and 93.0 (nightly) on my machine. Did you play with userChrome.css and broke it ?
Nope. I don't play with userChrome.css at all. I am just using the System theme.
Just found that I had the `browser.proton.enabled` false. Toggling it brought back the border. Wow. I completely forgot about this setting I changed around FF 87 or so.

PEBKAC :)

Still don't like the distinction between active tabs and container tabs though.

Can you go into a little more detail about how to resize it?

Sizeable means large. It's not the same as being able to resize it.
Don't forget, you can still use multiple profiles. I have multiple shortcuts setup, each starting FF with a different profile. Within a profile, I use containers to further partition things.
edit: for instance, I have a 'banking' profile with containers for each bank, brokerage, etc. The profile is totally separate from my 'general browsing' profile, so nothing can be sniffed. And the containers allow me to partition off each service

I use profiles and containers together in Firefox, which gives more flexibility than either of these features alone.
Firefox lacks a built-in profile switcher menu like the one in Chrome, but the FOSS browser extension called Profile Switcher for Firefox is a similar replacement:
https://addons.mozilla.org/en-CA/firefox/addon/profile-switc...
You'll need to install the connector for the extension to work:

What benefit do you get from starting another Firefox instance with a different profile compared to simply using a different container in the same instance?
Different profiles can have different extensions, so if you don't fully trust some extension you can isolate it to a given profile.
Also different bookmarks and different histories.
The ability to configure browser and extension settings differently for different profiles, plus different history/cookie for each.
This is nice for experimenting with changes to umatrix settings without having results "pollute" my long-lived container storage.
Also nice as a relief valve for when I don't won't to deal with my locked-down default settings, and just want to open up a site with everything enabled in a temporary container that gets blown away when I'm done.

Very interesting... The one nice thing about containers is being able to move sites from one profile to another if necessary.
Can you do the same with profiles? If I come across a link in one profile, but one to open it in another, is there a way seamless way to do it?

other the copy/paste the url? I'm not aware of one..though, that's not very 'seamless' :-) The whole idea is that profiles are totally separate - separate process, config, etc.
I always wondered why there was no easier way to change profiles in firefox than about:profiles. I am not sure what your solution is though, would you mind going into details ?
Thanks in advance
There is an easier way, if you are willing to install the Profile Switcher for Firefox extension and accompanying connector. See my other comment: https://news.ycombinator.com/item?id=28356472
You can create a shortcut which will launch with the profile of choice: https://support.mozilla.org/bm/questions/1171685
The problem is that this is the same solution as it was in 2005 and no average user is mucking about with specified shortcuts or command line flags. Chromium has demonstrated the most obvious GUI for this but for whatever reason the FF product team believes we should prefer about:profiles or this solution.
I launch my FF profiles from the terminal using aliases. But I guess some people would find that difficult (though it's not) even if they do happen to be a Linux user.
I just have a shortcut for launching with the -P (Profile) and -new-process options.
Good idea, i opened a private window with all extensions disabled for banking and closed the normal window. Like your solution even more.
Personally I love containers and I can't imagine using a browser without them. Though one issue which has been long standing for me is - tab search ('%') only works for current container. This is a big problem if you have 10-15 tabs open in different containers. Switching to tab you want is not easy. I wish mozilla prioritized and fixed - https://bugzilla.mozilla.org/show_bug.cgi?id=1479858
Firefox containers are cool. I do wish though that they were better integrated with the rest of the browser eg. bookmarks , history, downloads etc.
I am aware that I can configure it to open certain sites in certain containers always, but that is not ideal in many cases eg. using github/gmail for both work & personal use.
I currently use an extension [1] that enables support for opening links in specific containers using custom protocol handler. So now I can have a launch-gmail.sh script that invokes
firefox 'ext+container:name=Google&url=https://mail.google.com'
to open the site in a specific container.

One downside that I had hoped containers would fix was multiple accounts on AWS.
Because of the way AWS handles the URL's for logging in I get:

AWS.com/company3
I have the same issue, but I don't see the same thing.
I have bookmarks set up with URLs like your first set:
One solution would be to have FF containers tie into the bookmark editing code so we can set the container by bookmark. That is, when I click a bookmark with a container set, that container should be used to open the site regardless of the URL.

Have you considered using a password manager? With 1Password I'm able to save all logins for my AWS accounts and then just select the appropriate one when logging in.
I use pass (password-store). I haven't added any firefox plugin to manage that for me. So I always go back to the terminal for copy/pasting the details.
I could suggest browserpass. It should be clever enough, at least with search.
Same for me using LastPass.
I use different profiles for that...
basically, I have multiple Firefox shortcuts, each using a different profile. You can also use containers with the profile to segregate things even more.
I wish Firefox had better (chrome-level) support for containers. There's various small QoL things that add up to make them a much more usable feature.
At the very least, exposing them via webextension APIs would let developers take care of it themselves.

While Firefox doesn't have WebExtension APIs for browser profiles, the Profile Switcher for Firefox extension uses a separately installed connector binary to add a profile switcher (similar to Chrome's) in Firefox. See my other comment: https://news.ycombinator.com/item?id=28356472
Sounds like Containerise can do that
Are containers still necessary? Does the Firefox built in privacy (Strict privacy protection policy) provide same or similar functionality?
Those are for different things. I use containers to log in to the same website with different accounts without having to switch browsers or open a new window. E.g., since Discord still doesn't support switching accounts in the year of our lord 2021, I have a container set up for the discord account I use for IRL stuff, and my personal account logged into the "vanilla" container. I can keep both discord tabs open side by side and get notifications from both.
Even for websites that allow switching accounts, I prefer to use containers especially if the accounts go across different "domains" of my life. If I must log in to something personal at work or vice versa, I generally use a container for that to keep them separate.

I use containers to only use some google services while signed in. For instance I use gmail signed in but I google search in a separate container to not log that data in my account.
I may be fooling myself and google can identify it anyway through my IP or something but it feels like I get a little extra anonymity.

duckduckgo is a thing, just sayin
I use ddg primarily, but I regularly need to use g! to reroute myself to Google when searching for anything that I don’t already have domain-specific knowledge for.
Like if I want to just check syntax for a new programming language, ddg can handle the search just fine, but if I am doing initial research for a problem I don’t understand well, I need Google to get consistently relevant results.

But the search is not as good. Or good might be subjective in this case. But I tried using DDG mutliple times, but every time I end up just doing the same search on google becouse it is much better at giving me the result I want.
But this is just my personal experience.

Earlier this year when PS5's were really hard to get, I used Firefox Containers to help get one. One of the tracking services would tweet that some retailer had them for sale. I would use containers to open a dozen connections to the server. A couple containers would get through and eventually I was able to complete the purchase transaction.
It took about a week of trying and I was successful at Walmart and BestBuy.

Containers are necessary to provide account segmentation.
I wrote up a quick email to friends/family at the beginning of the pandemic about Firefox containers in regards to the vaccine signups that were occurring. Since there was site isolation you could get as many “slots” as you were willing to solve capchas. Most of my friends and family were vaccinated because of this feature. A bunch say they use it now a days for normal site isolation but I did at least convert some people off chrome that way.
Very clever use case
Wouldn't a private window achieve the same?
You would think but no. Open a private window and log into a site. Then open another and it’ll be logged in. Incognito windows share cookies. They are deleted once incognito mode is turned off but that doesn’t help us in our “open 100 windows at the same time to get a bunch of slots” use case here.
One issue I have when using containers is that if I have a non-containerised tab and I click a link in it that leads to Twitter, which I have a container for, a new tab opens in the container, but the current tab also switches to a Twitter tab with the click, clobbering my session/history.
Is this a bug or conflict with another setting or add-on?

this doesn't happen for me.
what's the other add-ons you have ?
I have things like CanvasBlocker, uBlock Origin, Tree Style Tabs, etc, and disabled third-party cookies. But nothing that should actively interfere with it. wrt containers, I have Multi-Account Containers, Containerise, and Temporary Containers. It happens every time I go to a URL that has an associated container I've made (YouTube, Twitter, Facebook etc).
I might try resetting my container plugins to see if I can clear it.

Fixed it. Containerise has a separate "Keep old tabs" setting that is different to the Multi-Account Containers "Replace tab" functionality. It works as intended now. Horray!
That's nice. thanks for sharing
I've been using Firefox Containers for over half a year now (I use it with the Temporary Containers[1] extension). For most parts, it's working great.
However, whenever I encounter pop-up sign-in pages, such as for older websites and some Firefox extensions, the resulting user session cannot be accessed by the original page or extension. This is even if I open the pop-up with the same container, or with the 'No container' option.

Alternative low-effort solution that might break some websites (only issue I've run into so far is U2F based 2FA with Duo):
privacy.firstparty.isolate -> true (in about:config)
Effectively acts as a separate 'container' for every website.

The problem here comes in when you have things like SSO where many sites auth to Google, or AzureAD, etc.
With Continers I can login to the same site with mutiple accounts, for example one common use it where you have a Admin Account, and a Regular Account. You can use FireFox Containers to access the same site(s) using different accounts
I also do this with Amazon, so I can have my Work Amazon, and my personal Amazon separated with out having to use the "Change Account" feature which I find to be annoying

Yeah, I agree there are definitely usecases containers address that FPI doesn't. However, if your use case is just "I don't want Facebook and friends to track me across websites", you should give FPI a try!
One of the unexpected benefits for me has been that I can lock any OAuth enabled app to a container for the OAuth provider I use. To login, I check which container I'm in and click the associated button.
Before this I'd always forget which OAuth provider I previously used. Did I Login with Google to DigitalOcean or did I use GitHub? Worse, I'd often click the wrong button and get logged into a new/empty account. I never came up with a good rule for which OAuth provider I should use, so it's a guessing game.
Locking the app to the container means I don't really need to think.

Containers are a killer feature for Firefox, like having adblocking that works on mobile (unlike on Chrome).
Just need containers on the mobile version.

There's a petition on ideas@mozilla for implementing containers in the mobile version of Firefox, if you'd like to vote for it: https://mozilla.crowdicity.com/post/721603
Trouble is it apparently requires a lot of reimplementation deep in the guts of the mobile app; they do understand it's a highly-desired feature.
>having adblocking that works on mobile
I thought you couldn't install adblock addons (uBlock Matrix) on mobile Firefox?

uBlock Origin works great in Firefox on Android.
The last times I looked at the Firefox Multi-Account Containers addon, the story for managing persisted data and cookies per-container was abysmal. Is it now possible to seperately manage each account's persisted data?
Do any Safari users miss containers and why?
It looks like tabs in private window (which are isolated in Safari) fulfill the role of temporary containers almost identically.

When will Firefox have a better UI for their profiles?
That's literally the only thing stopping me from switching to Firefox.
Google has an entire menu devoted to it.

The free and open source Profile Switcher for Firefox extension, paired with the connector app, adds a browser profile menu to Firefox similar to the one on Chrome. See my other comment: https://news.ycombinator.com/item?id=28356472
Yeah I can't believe they still have the same solution as 2005
about:profiles doesn't do what you need?
No the UI was really poor when I tried about:profiles.
I know, I know, probably a bit more than containers were intended for, but the containers thus far have been great otherwise. No need to open multiple browsers to test software quickly under multiple accounts, I can just login through all accounts I need to test on multiple containers.
Edit: The more I think about it, the more I feel as though Mozilla could find plenty of VPN (their own underlying provider included) providers to fund support for these changes to make them generic across VPN services and transparent.
