This extension is all I needed.
Major issue I faced is it fails to open the specific bookmarks in the designated containers.
Other is opening tab by keyboard shortcut is limited to only ten containers. If there is a functionality to increase that then this addon would be great.

the review nag is annoying, but the feature is great and works well

nice addon, could be rated 5,but the nag take 1 off.

Wish they would disable the "You opened 100 tabs!" message that appears every time I use a container now...

Very useful

Really nice to have isolation per container, and I've found great utility for it, especially when I was fed up with using Google account switcher for switching between different google accounts of mine.

Adicionei sem querer uma 'página interna' à lista de sites forçados de um container. Aparece um ícone de globo cinza e nenhum texto. Tentei excluir clicando na lixeira ao lado. O item desaparece, mas a exclusão não é salva. Quando volto a mesma lista, o item está lá da mesma forma. Além disso, uma opção para exportar as listas de sites é um recurso desejável.

ça serais sympas de pouvoir relier les containers à des groupe d'onglet ou de pouvoir cacher les autres container si on le souhaite

This is incredible add-on. For improve i recomend add "+" bellow each group of bookmarks for faster opening in container

This extension truly helps making juggling separate accounts far easier. The only thing that would make it perfect is if it could somehow store bookmarks separately for each account.

ichbin firefox zufriden

It works well for nearly 3 years. I am using portable firefox with multi-ac containers for nears 3 years, I have 10 containers, those of them have different user agent, but suddently, since yesterday, all containers share the same user agent and cannot set different user agents for each container alternately.

Excellente fonctionnalité !

Quelques soucis d’ergonomie ralentissent la prise en main (comme si les dev n'étaient pas encore sûrs d'eux et ne souhaitaient pas trop imposer la fonctionnalité).

Il manque par ailleurs une fonction décisive : la synchronisation des containers entre les différents appareils (à moins que je n'ai pas encore découvert comment faire ?)

A part ça, c'est vraiment une solution excellente pour nous permettre de protéger notre vie privée, merci !
