Tree Style Tab de Piro (piro_or)

The only and best way to have tree style tabs! So useful! Thanks!

use it for years, amazing tool, not only to show it vertically but allow you to fold pages related to a topic.

It automatically closes parent tabs sometimes, and it is really annoying

A colossal improvement over the standard tab bar.

Frankly, it's long past time we collectively killed the standard tab bar for good. The standard tab bar disgusts me.

I wish someone would make this for Android Firefox.

E: 5 yrs later, this is still say half of the reason I use firefox instead of chrome

please import this extension for chrome or opera or vivaldi, i cant handle firefox anymore

I please, you would improve more the performance
My PC Alienware 17-r5 Windows 10 (19041.450)
+ a search function (duplicate tabs etc. like All Tabs Helper)
Thank you

you get the 5th star if you mention (on the first description line / permissions list somehow) that you only want to send one notification requesting feedback in the future

Useful, Professional look, customizable and supports 3º party addons.

There is something weird compared to other vertical tab managers and is that there is no filter bar. I hope that there will be one in the future in TST or as TST's addon.
