One of the most useful add-ons ever.

A melhor opção de todos on navegadores/extensões para gerenciar várias contas. Bonito, rápido, simples e customizável.

Juste parfait... Permet de segmenter les cookies, d'ouvrir plusiers onglet vers le même site avec des identifiants différents (plusieurs boite mail par exemple).
Indispensable !!!

Essential.

Such a blessing! Especially in combination with the keyboard shortcuts add-on. Would be greater still if containers set up would sync over the Firefox profile to keep them in sync across devices!

usefull

I realy love this extension, it's what I always searched for!
One feature that I'd love to see is the ability to map containers with firefox accounts.
By that I mean I have a personal firefox account with a set of bookmarks and a professional one.
Firefox containers kind of overlap with firefox accounts. On one hand I can access all my bookmarks and on the other one I can separate concerns easily.

Maybe I'm missing something but that would be awesome instead of going about:profiles everytime.

Just works, as advertised. I use it to be logged into two different accounts in the same browser :)
The only feature that can seem kinda buggy is the "always open in default" which I understand to mean that new tabs will be opened in the "default" container, this is not the case and I haven't found a consistent pattern.

But that said, it opens links in the same container the source page is in, and it "just works".

One of the most useful add-ons available right now.
