Great addon and idea, but the sync is a complete sh*t show. When deleting containers, they just somehow reappear, and if likely you'll end up with TWO, since it seems to restore the one you deleted and then pull one from the sync. In short, the Sync feature is completely useless, and have left me with at least 5 duplicates of every container I tried to delete. Can you PLEASE fix this? And there's no way to purge what's stored on the cloud.

Best Addon. Can be a builtin in latest firefox browser.

Amazing feature! Allows a way more convenient way of managing different accounts from the same website and, at the same time, it is great that is an optional extra feature from the Mozilla Team. Recommended.

Helps me to login to multiple aws account without opening private window or another browser

Killer feature! The reason of my switch from other browsers.

convenient add

That's why I was looking for years. Thanks Firefox.

Linus tech tips would not have been "hacked" if he used this extension.

Containers on Firefox basically solve all the problems and limitations a software developer can have with other browsers. It just simply is awesome. Kudos!!!

Great add-on, that is a must-have. I can split my logins over multiple containers, and have sites that require MFA trusted from within the same browser for different accounts. Can't recommend enough
