menu bar fonts have a dropped shadow
The fonts on the Menu Bar (File, Edit, View etc) and the bar that has Most Visited, Getting Started etc. have a dropped shadow while the font itself is white. I've looked under "tools/options", but the font listed there isn't the one on the Menu Bar. I'm sure it's something simple that I'm not aware of.

Sounds that you installed a Persona.
You can uninstall your current Persona and revert to the Default theme (Tools > Add-ons > Themes).

I got the same problem and I didn't even install Personas. I disable firefox 4 aero, and I still have white shadows.
