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。

Bug report!
-------------

After I removed Firefox Multi-Account Containers add-on, the 'Open Link in New Container Tab' context menu item is still working!

I had to create an other Firefox profile without this add-on to rid of it!

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.

Funktioniert nicht

The idea and implementation is actually very good, but the UX is killed by the very restricted set of container icons and colors. You should allow us to go wild with experimentation about use cases. The builtin icon and color set should be at least thrice as blig, but for "power users" you should allow to take anything from an emoji/color picker!

Edit: I understand that these limitations exist in the browser's container implementation, not in this add-on. Therefore I don't want to be hard handed with the add-on, and bumped the stars to four. Still, the add-on is not a third-party independent work but a part of the implementation of the feature, so it's not possible to judge it isolated from the allover implementation. Thus I won't give five.

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!

It's great to be able to keep my work and home profiles separate, but which links I want to go to what profiles when I open them varies by machine. It doesn't play especially well with firefox sync yet (because the naive way is wrong! Context varies with machine a lot)

Opening new links and choosing a container is a little laborious.

Switching between containers when you choose the wrong one is tough too.

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. )

Interesting add-on.
It can be better with the capability to move a tab into another container.

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