Only rating 5 stars because I can't rate it 6. This is perfect. As a freelancer, I don't want to use Chrome's tedious login mechanism. This lets me quickly name my clients and split them into groups. It is Google agnostic and let's me use my current browser add-ons.

I don't know where this plug-in has been all my life, but thank you.

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.

I really like the concept and the smooth implementation into the Firefox browsing experience.

Läuft soweit ich das beurteilen kann gut.

Works great! Makes it super simple to separate websites into isolated groups.

Edit: I agree with Dan; would be happy to see containers integrated with Firefox by default.
