Update: This was done and it is absolutely amazing now!

Extremely useful and amazing. This is a game-changer for online tracking! The next step up would be to sync the containers between different computers with same login.

Absolutely genious! I can finally use google and multi account sites without logging in and out!

Totally addictive! For us who use manage multiple cloud instances, this is the solution to all browsing problems!

Easy to use. Open another 3 more dif browsers is my dark past. Now is no more. This add-ons deserves 5-star.

Genial!!!

It is incredibly useful to keep my privacy. It's a must!. Thanks.

Most needed. My only concerns so far are somewhat confusing flow of using it and lack of settings sync between different instances.

Love love love this addon. It does everything I need it to do and I don't have to have a bunch of different browsers open all the time.

For the developers: I would be even more in love with this addon if I could containers for my homepages so every time I open it, all my various email accounts pop up. Consider it an official feature request!
