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!

Works great. I do have to agree with another reviewer and say that being able to configure cookies and such for each container would be nice.

just awesome!

Everyone should use this.

excellent....helps me a lot to maintain my online shops with several user accounts....keep it up...

My computer is still hacking. I have a good idea who the person is. I can definitely help.

Very useful, especially for multiple accounts! Every Browser should have this out of the box!
