A extensão é ótima. Além de melhorar nossa privacidade ela me deixou mais produtivo (por não ter que ficar trocando a conta do e-mail sempre que for acessar uma conta diferente).

Helps you separate accounts and groups of accounts, even allows you to always open a site in a specific container

This is the main reason why I still use Firefox! Works perfectly (especially if you have to login to multiple O365 accounts, which can be brutal)

Love this add-on. It's been great with my work to keep certain sites separated from each other. I use multiple Office 365 accounts a lot for example and using these helps with the admin login persistence issues. Also helps isolate junk sites that could be intrusive.
