This add-on stops my Facebook and Google account from showing everywhere outside.
It would be helpful to remind users that it does not work when Private Browsing is enabled, since there are some people who enable Private Browsing all the time.

Very useful for privacy and security

I am a software architect, and quite often need to login to multiple sites with different logins, including Google to segregate between work and personal accounts. I'm in love with this add-on (have been using since its test pilot days). Very helpful!

Fantastic app that lets me open up work based tabs without interfering with personal tabs. Two Office 365 accounts? No problem! One container for each and away you go.

Saves opening different browsers just for a different account on the same website, especially the pervasive Office 365, which seems to be a right pain if you use two accounts with two organisations.

It's great extension!

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.
