This is one of my favourite addons. I migrated to Firefox completely from Chrome and other browsers due to this and mainly Privacy security.

With the new UI updated and the keyboard shortcuts for container tabs, its even more awesome. The update had some confusions, because there werent proper onboarding for it. Once its setup and we know how to use, its better now.

I miss the following things still :-

1. Sort the container tabs in the container menu. This is a basic feature which is missing I guess.
2. A shortcut to open a new tab in the same container we are currently in.
