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

The best add-on of Firefox!

An incredibly useful extension that allows me to use multiple different logins on the same site by using different containerized tabs, a must-have feature.

I wish containers could be organized and customized a bit better, and I wish the rulesets could be changed more easily, such as removing sites from "Always Open In" lists and allowing exceptions to such lists after they've been made.

Lovely extension that allows me to surf the net more privately

Excellent plug-in. A real productivity buster and super useful to compartmentalize browsing activity
