Maybe try the Classic Theme Restorer to see if that works and check the CSS code that this extension uses. The styling of the Tab bar is quite complicated and may also not be stable across releases.

I've called the big guys to help you. Good luck.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options)
key, and then starting Firefox. Is the problem still there?

Thanks! There is no problem in safe mode, because the userChrome.css doesn't get populated in safe mode. However if i delete all the extensions(also if i do "refresh firefox") the problem doesn't go away. As soon as i add the userChtome.css the problem is back. Therefore my userChrome.css is not correct, but i don't know there and why.
