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

This is my favorite extension since 2003.

A complete overhaul about tab controlling... It becomes one of the reasons that motivating me to keep using Firefox today (with no exaggeration :P

(Fixed, with extreme swiftness. More congratulations)
Piro, the savior of Firefox. Many, many thanks.
But I think version 3.5.7 broke TST Hoverswitch, equally fundamental for me.
