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.

Recently it's been impossible to remove a site from the 'managed site list' - after a short period it re-appears. Perhaps its an integration issue with FF sync, or occurred when FF revamping the profiles management.

Excellent solution to manage multiple cloud tenant.
