Useful, polished, heavily customizable. Overall an amazing extension.

This add-on made me change my entire browser experience, once and for all.

I was fighting with tabs for so many years. Constantly having a multitude of open tabs, fearing accidentially closing the window.

I was not very productive, having to scroll and look for tabs all the time.

This add-on was recommended to me, and while it did take some getting used to, I was finally able to conquer the vertical tabs.

Now I've move on from Tree Style Tab, to the more powerful Sidebery, but this is what made me do the jump.

This add-on is the reason I still use Firefox. I salute Piro for keeping this extension going despite Firefox challenges. I really miss auto-hide. I've been having a lot of trouble lately with selecting the folder when I bookmark a tab or tree. The folder box has a - in it, and when selected, pops up an empty box which doesn't respond. Has anyone solved this problem?

Piro is a tab GENIUS

Thank you for your tireless work fighting AMO failures and mozilla defects

Ability to place a new tab button in the top bar

If I had to choose only one addon with my Firefox, it would be Tree Style Tab.

love it!

Excellent for me. Very customizable. Only slows down the pages even with multiple tabs. Without it the speed is OK.

SUPER.Ein echtes must have.Vor allen Dingen auf dem Laptop unverzichtbar.

I've been using this add-on for a few years and it helps me navigate the many tabs I tend to have open in my windows. I've never had a problem with this add-on.
