Extensão excelente para quem, como eu, sai abrindo várias abas a partir de uma. Permite não só fechar todas de uma vez como também organizá-las de forma simples e rápida.

Tree Style Tab de Piro (piro_or)

Honestly changed my life.

Amazing! I use it for years and it only gets better with time :)

Works extremely well, thank you. It's overdone, but that's okay.

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.
