This add-on is game changer for me. Without this, I had to run a lot of dedicated profiles with FF, which was counterproductive.

Wish this container add-on was available for mobile too.

Thank you Mozilla for this great product!

An absolute must-have when you have more than one Google and/or Facebook account.

Extrêmement utile... stable et simple

Not that this needs another review, but this is one of Firefox's really killer features. It's like having separate browser profiles, but soooo much simpler to use.

I use one for each Client I do dev work for to keep the SSO logins separate. So, when I switch from one client to another, I don't have to specify my user every time on MS sites, etc. Every time I go to a website that uses SSO, if I'm in the right container tab, I'm logged in and ready to go. It's saved me so much time and headache.

Like, I have no clue why some of my dev coworkers are still on Chrome/Edge/Whatever Chromium clone. This feature alone is enough reason to come to FF. (To say nothing of the other great stuff, including the extremely important mission of "preventing 1 single company for-profit business from controlling the future of the browser. (i.e. even most alternatives use Chromium, which is "open source", but really controlled/developed by Google.)

Switched from Chrome for this extension, love it.

i dont know what the guy from 2 days ago was talking about, for me this extension somehow bypasses the youtube adblock detection. superb to the highest order

I just recently added VPN. Thus far, so good!

good extention, i can separate tab and configuration that i want

Has anyone else noticed this add-on now breaks YouTube since YouTube started looking for ad-blockers? I turned off uBlock Origin figuring that would fix things, but nope. If I have youtube.com containerized using MAC, the site still complains thinking I am blocking ads as well.

Great addon! To the user who asked 12 days ago: you can delete a site from a container in the extension: press on extension, press on manage containers, choose one, press manage site list, delete the ones you don't want to open in a certain container:)

it was great!

Extremely powerful

There are no equivalents to this addon in other browsers, and no way for me to overstate just how important it is to have on the modern web. Developers can see how a site looks for five different users without needing five browsers open. For users with multiple accounts on the same service, you can do the same thing.

Multi-account Containers is an indispensable tool, and only on Firefox.

Plus besoin d'ouvrir un autre navigateur pour ce connecter avec 2 comptes en même temps (un adm un utilisateur) sur sur un site.
