Genuinely one of the top reasons I use Firefox.

It must be killer feature of Firefox!
But there are some issues:
* Ability to edit domains assigned to container (not via deleting them and re-adding new one)

It's a very convenient and good tool. Will continue to use.

Would be nice if you could sort your containers you have already created A-Z other than that awesome tool.

Absolutes must-have!

Amazing, just so amazing, seemless, and smooth! I love it so much! It has made my life so much easier! HIGHLY recommended if you have multiple emails or just prefer different profiles for different work.
