Scrollbar bug screenshot.

You can see I am at the top of the page but the scrollbar is at the bottom.
Reproducible about once a day.  The scrollbar updates its position either after ~5 seconds or after clicking into a different window and back.  One can scroll by mouse dragging the scrollbar, by the mouse scrollerbutton or by PgUp/PgDn and the scrollbar remains not updated.
It is a Firefox 17 regression.

I have this bug too.  I use xfce + sawfish also, so if the whole world isn't seeing this bug it's probably specific to sawfish.

firefox-17.0.1-1.fc16.i686 shows this bug for me.  Downgrade to firefox-16.0.2-1.fc16.i686 fixes the bug.

I don't see any F16 updates yet in the main repos so I am using 16.0.2.1 for now.

It is most probably fixed in firefox-18.0-1.fc17.x86_64 / xulrunner-18.0-6.fc17.x86_64, at least IIRC I have not seen it so far.
