Very useful extensions, especially when you have multiple accounts on a site and don't want to constantly log in or out or when you just don't want a site to access data from other sites you visit on your main profile.

It's only because of this extension that I use Firefox. Cool feature. There is no such option in any browser.

This is one of the core plugins I use (in addition to Ublock Origin).

With the account sync, containers are also remembered across different computers as well, so I don't have to set up the containers on every new laptop or reinstall of firefox. Sometimes I mistakenly open a website in the wrong container because I don't always map every single website to a container, but most of the time it's a non-issue.

I'm surprised this is still an add-on and not a core Firefox feature.

Very usefull addon, perfect

It doesn't work for me. I cannot create a container where I am logged into Google and simultaneously a container where I'm not logged in.

L'add on correspond parfaitement à ce dont j'ai besoin

A must have, cannot imagine my workflow without it anymore.

Very handy for managing multiple M365 or Google tenants.
For me, the only thing missing is the ability to have “private browsing” containers and a way to always open in a container, for example when editing a bookmark.
