From a technical point of view everything works great. I never had any issues.

From a user experience point of view, I love it. I use it to log into various Office 365, JIRA and Amazon Webservices instances for various fields of work: my own start-up and some other freelancer engagements. Since each tab is a separate container, I can sign into the different accounts at the same time. Before, I would use Chrome for one engagement and Firefox for the other.

The add-on is amazing and works seamlessly, and now it feels like an essential for everyday use; but it could still improve, for example, by including more icons, or letting us choose colors from a color picker, instead of a limited set of default colors.

Can't believe it's taken this long for this kind of feature to come to the web. Absolutely must-have feature, kudos Firefox team! Please keep developing it, it's a solid start.

Awesome ! Would it be possible to provide a shortcut to quickly reopen a tab in a container ? through right click, with an optional toolbar button or even embedded in the existing widget at the top right. Thanks !

Amaizing!

Sometimes the scripts of certain pages that are contained in one container are used in the pages of another container making some kind of Cross-Sripting and blocking pages such as Wikia.com and many others. Basically it's because most of sites are interrelated.

As well that when a link is opened from inside a contained page that link is contained either and not independently from that domain containing.

And now it just logs out my accounts that were not in a container and later I tried to log in to them in the default container instead, and actually can´t mark to open them always in the default container.

I would like suggest a feature. It would be better if we can add subdomains like *.wordpress.com, *.blogspot.com to open always as in a specific container.

le fait de pouvoir assigner un "container" par défaut pour un site donné de manière automatique est appréciable.

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!
