This great addon is the main reason why I'm using Firefox.

導入してからタブを探し回る事が減りました。

サイドバーにタブを表示するアドオンは他にもいくつかありますが、複数の階層に分けて分かりやすく整理できるものはこれだけだと思います（派生型を除く）。

Vivaldiのようにサムネイルも表示できればなお良し。

希望能够出一个chrome版的tree style tab，感谢作者。
Hope there is one in the chrome, thank you, great author of great plugin

My favorite extension of all time and thanks for keeping this up to date!

Can you hide the browser's own TAB bar？

Mil gracias por tu trabajo Piro, no puedo vivir sin esta extensión.

I love it, it really changes the way you use the browser. If you have a ton of tabs it's so much more organised and you can have lot of tabs for different projects and not get lost.
Though I would love it even more if there was an option to save a tab group for later and easily restore it. Thanks for making the addon and hopefully you can add this feature sometime :)
