One of the killer features for Firefox.

this extension is great, would be even better with a way to look at/manually edit the automatic opening in a container

this extension is great. lets me sync Firefox across work and personal computers but keep logins (like gmail and such) separate

Brilliant! Really good job! Feels like i don't need another browser. Keep up to date, and thank you Firefox!

Excellent add on, no more private tabs / other browsers needed

Просто Must Have дополнение🔥.
Ощутил абсолютный восторг от использования, сравнимый с тем, что был при первой установке адблока. Вот прям настолько круто👍
