Must have addon!

Thanks for this very useful add-on, I could not use firefox without it anymore!

Amazing extension I couldn't do without. Only gripe is that when focusing (left click) on a tab it sometimes moves it to a new window. Only happens on macOS though.

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
