Honestly changed my life.

3.7.3 is broken - no more working. No reaction left mouse on Tabs. I went back to 3.7.2 - perfectly working.

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.

Works great! Only thing missing is I'd LOVE the option to be able to see tabs / trees from all open windows and not just the currently focused one. Is this possible?

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.

Firefoxに欠かせないアドオン

Does it have shortcuts?

It's really a useless add-on. It doesn't reduce the tabs at all.
