Reporter, do you still see this problem with the latest Firefox 2? If not, can you please close this bug as WORKSFORME. Thanks!

I still see the problem, Firefox 2.0.0.4.
The error in the Error Console now points to line 1151.

It's because we try to scroll the tabbar before unsetting the collapsed attribute. http://bonsai.mozilla.org/cvsblame.cgi?file=/mozilla/toolkit/content/widgets/tabbrowser.xml&rev=1.230&mark=1171,1172,1215,1216#1163
Is there a reason you've added this CSS?

Yes, I wanted to use it in one of the Firefox themes I'm maintaining. It was a good solution, but I didn't used it because RTL users will suffer from this bug and therefore couldn't use my theme.

Is there a chance this will be fixed for 3.0?

This bug was originally reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.8 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME

Seems ok under XP using 3.6.9 & RTL language pack.
