This addon works very well to separate state between different accounts. Much easier to have work and personal mail tabs open in different contains pinned in the same window than to have multiple windows open.

Good for increasing Privacy/Anonymity online by compartmentalizing tabs into their own little virtual sandbox of sorts.

Sadly, demoted from ☆☆☆ to ☆as of 7 July 2021. Starting ten days ago, the extension was unable to associate different logins to a domain with my different accounts: Google Drive was always personal, or always work. Since Independence Day, it's been trying to fix that by jumping frantically back and forth between different containers in the same tab - window jitters like crazy, and your only option is to close the tab. Today the jitter spreads to previously stable tabs when you close a schizophrenic one. The only solution: turn the extension off, and lose all the walls between different roles.

This is a great idea, and I hope the Mozilla team figures out how to make it WORK RELIABLY. Meanwhile, I'm going to be making a lot more use of Chrome personas.


When I gave this add-on a five-star rating, (see below) I didn't realize:

IF YOU TURN IT OFF, ALL YOUR SETTINGS GET WIPED OUT.

I had a couple of hundred URLs associated with my personal, work, coding, educational and Facebook IDs. To see if add-ons were making Firefox a memory hog, I turned them all off. When I reactivated Multi-Account Containers, the only associations that remained were with "Personal" and those were all wrongly linked to my coding persona.

So now I'm wondering if I want to take the trouble of rebuilding — at least a half day of work to undo what should never have happened. If Mozilla security protocol means an inactive add-on can't retain any data, there should have been a CONSPICUOUS WARNING of what I was erasing.

=========earlier review=========
If you are an admin — Google apps account, a Facebook page, whatever — you can finally sign is as a user/visitor at the same time you're editing, in side-by-side tabs in the same browser. And it's nice to have access to a persona not associated with any of your social media or email accounts, so you can escape tracking and junk email when you browse.

This is an excellent plugin but it suffers from not enough administrative interfaces being exposed. To use this addon successfully I'd need an interface where I can manage the auto-open-in-container lists easily and quickly. I've also run into a few problems where auto-open hasn't kicked in, and I've clicked a link and been left wondering why I'm logged out/logged in as a different account. Cheers.

Great tool! It's possible to "save" the websites-cookies-login of the tabs? It would be great to start firefox, press on each personality and open the urls associated with each of them with the logins (google accounts, facebook, twitter, pinterest, etc.). It would be the perfect tool for account managers like me.

Rozszerzenie służące do oddzielenia kont na prywatne, związane z poszczególnymi stronami do zakupów itd., które pomagają przy używaniu wielu danych do tych samych serwisów. Dodatek jest przyjemny w użytkowaniu, można także ustawić, które strony mają być otwierane za pomocą poszczególnych profili - a na pasku z kartami znajduje się pod nimi specjalna "wstążka" z odpowiednim kolorem, który wcześniej przydzieliliśmy. Pomysł, który powstał przy pomocy użytkowników Test Pilot, wypada bardzo dobrze :).

A superuseful add on by mozilla. A shortcut feature would completely kill the show here though.
