Instead of open many windows like Chrome, this extension make me feel a bit control because it's happened in ONLY ONE windows.

The best addon ever, convenient tabs and seamless proxy support

This is a must have for me and the reason I still use Firefox. The ability to have my email open in one tab and my administrator account in another tab is just one example of why I love this extension. All web browsers should support this by default.

thanx

Awesome

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.)
