Works out of the box just like a charm, though also extremely configurable in conjunction with Simple Tab Groups. A must have!

this is that I have been waiting from some time

Exactly the functionality I've been waiting for for a long time! Works great!

I think it most useful addon for developers! Right now I don't need to keep second browser while testing different users.

This extension is just so much useful. Firefox + this extension = Google does not record NOTHING of your online activity or history

Perfect concept for our actual way of connecting to the web !

perfect for separating my school, work, and personal emails, as well as managing my logins on websites where I have multiple accounts. Intuitive, streamlined, and reliable.

This addon has a lot of potential, and it could have many interesting features like setting or displaying user-agent, cookies and history independently for each container.

I hope it will be maintained and more advanced features will be added.

The #1 feature that keeps me using Firefox. The ability to keep personal info sucking websites walled off in their own sandbox is invaluable.
