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.

The idea is great, it worked great. It took me weeks to finetune everything and really think about what I would like to open in which container. Had a few problems with webshops opening in one container and the bank to pay in a different one. Also quite a few 'prove that you are who you say you are by clicking the link in your email' type of situations, which were opened in the wrong tabs. Everything in the end worked great! But then I had a problem with firefox and decided to refresh firefox. Normally not a problem, due to sync I have all my settings back within a few minutes. But every site was opening without containers. I waited and waited and waited and waited... Yeah, no link to sync. Bye bye weeks of work to get 12 containers work brilliantly.

Since one of the most important functions is completely missing... only 2* otherwise 5*
