Must have. It's really awesome feature.

It's really useful to be able to separate containers, but I really miss the feature to open tabs using CTRL+T that still are in the same container as the previous one. Example: if I'm in a tab in the Personal container, I want to be able to press CTRL+T to open a tab in the same container. Using the button inside the plugin icon takes time compared to just pressing a keybinding

非常方便好用。

很好用的扩展，能在同一浏览器里添加多个账号

I have created separate containers for Google, Facebook, Yandex, Linkedin and my streaming websites and liked the idea of behind it i.e. isolating different accounts and trackers. I would like to see more features (e.g. private tabs) in the future.

Yessssss!
I mostly use it for development to be honest. But I usually use at least 2 accounts when developing/testing so it's really really useful!
Plust I don't have to worry about FIrefox remembering stupid test accounts when I'm online outside my job :P

I use it to keep work tabs separated and to use things like google docs for several different logins. Very helpful

Containers are super useful for keeping work separate from personal projects and the like!

indispensable pour protéger sa vie privée

Super diese App LG Marcel

Love this for my development workflow and testing wordpress sites. Logged in/out.

This is useful for keeping multiple accounts for the same service separate. (Personal vs Work and such) Also useful for managing things I am and am not comfortable with sharing with people I might show on my computer. This is awesomeness incarnate.

(Although syncing containers between different devices through Firefox Sync would be even more awesome, it was really easy for me to set everything up without that. )

Awesome Add-on.
Would like to have this Add-on also for 'Firefox for Android'.

Now it's easier to login on multiple accounts

Simply... a must have add-on.
No more multiple browsers, no more cookie cleanup, login/logout cycles. As a bonus, keep tracking domains alone in their own container

Very practical to separate concerns. Should probably be natively included. Thanks to the developers

Easily one of the "essentials" you must have for an efficient workflow esp. if you are a super-user.

must to have add-on. it would be even better we can open a new window locked with a container

Very Good! I use it a lot! Thank you Mozilla!

Good apps

Very easy to use, and does its job perfectly. Would love some more icons, but definitely doesn't take away anything.

Its the best thing from firefox I have used in a while, keep it up guys
