Work. Three client accounts. All on the same system. For a couple of years now they've had colours and names. Problem solved.

Lol it must be not reopen it must be refresh, also it must be refresh right and left tabs with container, all you need to be teached:) Good extension, thanks

Must have!

This is THE little thing that puts Firefox 1 step above every other browser out there. This is like Chrome profiles on steroids. I can't function without Multi-Account Containers anymore.

this is great! now I can use multiple accounts on a website, in the same browser.

a very amazing addon for firefox made me enjoy my switch to firefox and made it even easier to use. its a must install addon if you are just starting to using firefox.

Amazing addon, very helpful. I actually started using Firefox more often just because of containers. Wish I could reorder Container Tabs in settings as to do that now, I need to delete and re-create to change the order, which is not practical. Other then that, works like charm!

Best Ad-don ever - bar none!

Best Firefox add-on
