Once you go Tree style tab, you don't go back !
Works fine on firefox 84.0 on kubuntu 20.10, thanks a million for this extension !

This is one of the extensions that just works! I can't imagine using Firefox without it any more. Thank you Piro!

The only way to organize your tabs nowadays, with wide displays, and height being limited. Thanks a ton to the developer

Makes life so much easier! Love this extension!
