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'.

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

It does what it says, but some things are a bit "funky". I'll keep playing with it and see...

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.

I've been using the built-in Containers in the Nightly browser since they first became available. Admittedly they are a power-user feature or for those that are vigilant about privacy/tracking.
I recently switched to this extension (over just the builtin version) to get the "Always open in container" feature which is pretty much indispensable due to external apps firing browser links (slack, email).
I wish there was regex/pattern matching support and literally any interface at all to see existing settings. The CookieAutoDelete extension has a great UI for managing cookie regex settings per individual containers - please implement something similar for this extension!

very nice add-on. i managed to log-in multiple accounts and never had to repeat logging in again but i hope we can password protect it so that other users of the computer wont hack the accounts in it.
