Parou de funcionar!

Excellent addon.
But doesn't work since Firefox 89.

Not good enough! Settings are not synchronised. Better shortcut expected. Atleast open new tabs in the same category which I'm currently in.

Good, but history settings are the same for all tabs, so I still need to use multiple profiles (firefox.exe -no-remote -P "profilename") to do the job.

I have Samsung j16 (firefox 57.0.4) but says incompatible platform
But this page says it should be compatible

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.
