I need to use two different Outlook / Teams accounts at once in my browser for my job and in this case, #Firefox Containers is the thing. With two clicks you can start new session of any service fresh and don't have to login again and again in incognito mode.
In case you wonder how to use it - right-click the new tab button and choose a new context you want to use. That's all.
Just wanted to share, maybe not everyone here is aware that this thing exist 🦊
