Could use some improvements, like a panel where you check all overriden domains (as if you override imgur.com it will always redirect to imgur.io, making it impossible to undo without disabling the extension) and a "simple mode" that allows switching only between desktop and android UA.

By changing your user agent to Windows / Edge, Microsoft Teams works like a charm on Linux :)

Worked perfect for me.

Practical, especially if you want to upload something from your PC to Instagram. Even now, when I want to use Teams in the browser, I can do so despite Microsoft's disabling, because I pretend to be on Edge. I noticed that the Chromium-based Edge is still missing and only the old one is available.

where is white list/black list domains? so, its only full switching for all sites?

GUI awesome, but ...(

Good

Easy to use. Facile et agréable utiliser.
