Due to a bad extension i think. See if anything at http://kb.mozillazine.org/Gray_bar_below_status_bar helps you.
I've disabled all extensions, restarted and the problem is still there. Same result starting in safemode. Tried all options from the KB article, still no luck. I've created a new profile and the first screen with the "make new account" wizzard already has this "problem".
