Best Firefox's addon in my opinion. It's very useful.

Love it

I would love to have a shortcut eg. Ctrl+G to open a menu that lets me select the group for the new tab.

I use it to log in two or more Google accounts in different containers while still being able to search anonymously in a default tab when needed. This is really great !

It would be even better if the menu allowed to open a standard default tab in addition to container tabs, though it is still possible by pressing Ctrl+T.

There is countless great things you can do with Multi-Account Containers to control your privacy and use multiple identities in the same time. It even helps you to keep your tabs organized.

I highly recommend it if you like to keep many tabs open.

Containers is very useful, but I think there are two point inconveniet:

1. "Sites assigned to a Container" does not support match patterns (*), so you can't add *.example.com and you have to add subdomains one by one : (
2. The page "about:preferences#containers" is useless……

Pretty good

fantstic does the job well and the tabs are neatly arranged in one large window

It would be great to have keyboard shorcut binding to open a tab of specific container!

I love using containers. They are simple to use, plus you cant be tracked

I LOVE this add-on. It one-ups Chrome's multiple user profiles since I can have a Production tab and a Beta tab right next to eachother in the same browser window instead of across multiple browser windows. I'd love the ability to have more colors (I'd especially like a "pure red" for "Danger") and a few more icons. But overall I love it! At this point I can't imagine working any other way without it.

I honestly could not do my job without this extension. Never get rid of it.

Innovation at its best

Love it. Perfect for separating work-accounts and private-accounts

Containers has simplified my use of Firefox where before I ran multiple browser profiles to be logged into different accounts, now I can run all of them in the same window. As a side benefit I can more securely isolate websites from each other.

excellent!!

Great idea but it doesn't support sync. I don't know a single person that only owns one computer. I'm not sure if Mozilla has product managers or if prioritization is all done adhoc via developers, but please, someone, make container settings sync a priority.
