There is no option to multi login on same contanier, like 1 gmail account to personal and another for work...
It's a very nice idea of thw extension, but is missing a few useful functions that you can only have on google chrome like this one I said.
Another thing is that even if you add any adress to your container and when you try to open it with your saved favorites adresses,you will have to save again site bye site to when you open it form your favorite bookmarks, it load on the exactly container that you want, otherwise it never open on the correct tab that you configured.

I love the idea of Firefox Multi-Account Containers, however, this add-on requires much improvement. First complaint: I created some custom containers, as opposed to personal or shopping, which have now vanished twice from existence. I use the Facebook and Google Container Add-ons [which work great!] in conjunction with this Add-on, but that shouldn't be a reason for losing my custom containers. The worst part of the vanishing act is that I have no idea why this is happening. My second complaint is that adding a URL to a container is too cumbersome. You should be able to right click on a bookmark and add it to a container, just like you can open it in a new tab, window or private window AND you shouldn't have to confirm that you want it opened in that container upon your second visit to that URL. As it stands now, first you must open a blank tab in your desired container, then click your bookmark or enter the URL, AND THEN CLICK A CHECK BOX ON THE CONTAINERS BUTTON TO ALWAYS OPEN IN THAT CONTAINER, AND++ upon your second visit to that site, you're forced to endure a needless delay screen where you must click the check box confirming your desire to always open that URL in the specified container. Fix these 2 problems and I'll give this add-on 5 stars, but you'll only get 2 from me today.

Should integrate Containerise (manually add sites to specifice containers) and Temporary Containers functionality.

I'm having a LOT of trouble getting 2FA to work in containers...as in no luck so far. I can see that I need to be adding specific other sites to the container in question so that the "circuit" can complete, but FFS I have been adding a metric shit ton of google sites and still can't get thru a basic 2FA on my google account. Is there a list anywhere of what all needs to be added to a "google" container to complete the 2FA? I had this same problem with the "Facebook Container" specific one-- so it looks like you guys didn't think to automatically add FB's 2FA sites to the customized one either? I can't be the only one trying to work this out... Would likely rate this much higher if this info were available somewhere (it's not obvious, I've been looking thru the addon page without much success for documentation)...

It works as advertised. However, if you use multiple computers, then you have to go through the setup process for each account on each computer. Either sync through Mozilla Sync or provide the capability to export/import. Dozens of accounts on multiple computers qualifies as a real pain to get the protections this extension provides. Please fix!

Syncing to my account got messed up, everytime I try to reenable sync it messes up my containers and I can't fix the data stored by Firefox Sync. Uninstalled.

1-No sync with firefox sync.
2-No Mobile version

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.
