It helps me organizing what I am doing by allowing me to add colorful tabs with customized symbols.

It also seem to divide the cookies in between the tabs.
I do believe it works because if an email account is open in a tab with a color, it does not open in another tab with different color.

However, when deleting cookies, cookies of all tabs are deleted all together.

Das Addon macht genau das, was es verspricht. Trennt die Surf-Umgebungen in einem Firefox.

I'm a software developer and I need to login into the same site using several accounts at the same time. Before I was using several browsers - super inconvenient. I love this add-on! Keep it up!

works well

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!
