Great add-on for browsing and keeping privacy data separate in different containers. Ability to clear cookies, history etc by container would be a great addition and worth the fifth star.

Very nice addon, resolves cookies sharing "issue", works nicely with Tree Style Tabs!

Love it!
Would be nice to define a specific container for a new tab

This is a good tool. It helps me a lot to maintain my personal accounts separated from my work accounts.

The best add-on of Firefox!
