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.

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