Very useful if you have multiple accounts for different sites. I use it all the time!

It'd be nice to be able to open in a new tab based on URL matching, not just domain

Très pratique pour séparer les sphères d'activité.

Fonctionne très bien à date, très pratique à différents niveau, par exemple, pour pouvoir tester des sites avec différents niveau d'accès simultanément.

It is exactly what frequent users of Container need. I really like the feature of always opening specific sites in a container, it is pretty useful for saving yourself a few clicks which makes life better.

Works very well. Can you add options to add containers to folders ? this will help us grouping the containers and keep the list compact.

This add-on takes Firefox to another level. Great job!
