Perfeito.

Vraiment très pratique.

fantastic! thank you Firefox!

This is a very useful add-on for separating accounts by category, using the same account in different tabs without the need for a private window, also, to ensure privacy, you can use this in addition to Total Cookie Protection in Firefox.

Excellent concept! It adds to my peace of mind, and is easy to get started with and maintain. And I love the way it integrates with Facebook container. But a feature request, if you please: To specify top domains for a container, and have all pages under that domain and its subdomains, open in the container, instead of having to add each and every subdomain as they are encountered.
