This extension truly helps making juggling separate accounts far easier. The only thing that would make it perfect is if it could somehow store bookmarks separately for each account.

ichbin firefox zufriden

It works well for nearly 3 years. I am using portable firefox with multi-ac containers for nears 3 years, I have 10 containers, those of them have different user agent, but suddently, since yesterday, all containers share the same user agent and cannot set different user agents for each container alternately.

Excellente fonctionnalité !

Quelques soucis d’ergonomie ralentissent la prise en main (comme si les dev n'étaient pas encore sûrs d'eux et ne souhaitaient pas trop imposer la fonctionnalité).

Il manque par ailleurs une fonction décisive : la synchronisation des containers entre les différents appareils (à moins que je n'ai pas encore découvert comment faire ?)

A part ça, c'est vraiment une solution excellente pour nous permettre de protéger notre vie privée, merci !

Great extension! I wish I could use my own uploaded icons and choose from a wider range of colors instead of the limited options provided. Additionally, due to the limited color choices, it's difficult to determine if a container is the one I need, and the other options don't work as well. I would appreciate a small title, similar to the bottom of spreadsheet tabs, overlaid on the icon color. We have Retina and 2K+ displays. Also, opening up a new container always in it's own window too could be helpful. ie research window next to wasting time window, etc without pulling tabs off to separate. Thanks, y'all!

Works great in general. If you are using containers combined with proxies or VPN, be advised that Service Workers ignore container settings. Hence, you might be generating traffice outside of the proxy/VPN you think you are using.

好用的扩展，但是中国大陆无法使用。

Separating FB from Instagram is tricky (Have the Facebook container extension too, that comes default with FF). Since it wants to always open those websites in the container. Managed to separate them the first time but somehow it kept erasing the Instagram session at every restart of the browser, didn't know how to restore that so had to nuke the container and start over.

I have 2 profile, cannot open gmail from profile 2 when it redirect immediately to google account on profile 1, No feature to disable that situation

Excellent extension! But can it please stop asking (and asking again) for confirmation to open a given web site in its previously defined container, each time Firefox upgrades to a newer version?... That's more than irritating.

I use this add-on mainly to reduce tracking by Google search. I.e. when I use Google search, I don't want to be auto-logged into my Google account or associated with my activity in Gmail etc. My laptop has 3GB of memory, it generally cannot handle more than one container running at a time. Instead of opening every google service in a container, I just have a container for Google Search and another one for Amazon (I'm not a big facebook user, but if I need to log in there I do so in a different browser.)

This arrangement surely makes my browsing less private than it could be as I'm logged into gmail etc w/o a container; I also have to ctrl-click links opened from google search and gmail, otherwise they open within the container.

I rated the extension 4 stars because I would appreciate an option to open outbound links (like google search results) outside of the container, without having to ctrl-click each time. I kind of wonder why containers aren't built into FF? But with the extension installed, the functionality feels baked in.

Found a bug: I have a container for Facebook (and only Facebook) that is set to "limit to designated sites". When I open a new tab and go to instagram.com, the browser gets stuck in an endless loop of opening the tab automatically in the Facebook container, closing it (because it's not facebook.com), opening it in a regular tab, and then closing it (because it thinks it should be opened in the Facebook container). Please fix.

Addendum: Please add support for manually rearranging the list of containers. Thanks!
