Multi-account containers is simply phenomenal. It helps with neatly segregating different portions of our internet exploits, a feature that at least I thoroughly enjoy and appreciate.

Very organized and serves me well

I like idea that Mozilla tries to move some of the power user functionalities into add-ons making the browser more lightweight by default.

But I really missed this feature, when it was removed and just found this add-on today.

Can't sign in using FB oauth on other sites when inside container

It's almost a 5 start review. I would appreciate a streamlined way of opening new tabs in a container. And maybe, if at all possible, having a setting that would allow to open links coming from certain apps in specific containers would take this extension to the next level.
Otherwise it's a great tool to keep my multiple work account that depend on gsuite login apart from one another and (for the most part) always logged in inside a particular container.

The icon not appearing in my browser. I can't find the setting to enter the Dashboard. So bad

I love containers, hope they will be here for ever
