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.

the best firefox feature ever

This extension is one of the main reasons I use Firefox.

Es de las mejores ideas que he visto en años. Muy bien hecho!

Excellent now that some bugs are gone :-)

Sangat membantu Penguasa Akun. Mantap.

Must-have add-on for Fire-fox

Another MUST HAVE extension for me. I don't want websites checking every other website I ever visited. So I gave them all a container to live in.

This is less important now that FireFox offers Cookie Isolation in Privacy settings, but it's still useful as it allows me to have multiple different accounts logged in for the same website at the same time.

I can't browse the internet without this extension. It's very useful and reassuring...

best one, helpful
