It must be killer feature of Firefox!
But there are some issues:
* Ability to edit domains assigned to container (not via deleting them and re-adding new one)

It's a very convenient and good tool. Will continue to use.

Would be nice if you could sort your containers you have already created A-Z other than that awesome tool.

É boa, mas precisa de uma opção para abrir sempre em algum container.

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.

I find the app excellent and effective, but I would also like to signal that, when synching from a different Firefox browser operating in another language, the basic containers like work and bank were duplicated for the two languages, and that should be fixed. Keep up the good 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!

Almost everytime Firefox have update, All my containers Disappear. WTH.
