When visiting gmail and sometimes facebook, on my mac, the page doesn't load fully and I get an empty old styled alert box that cannot be closed.
It seems that when I visit gmail, occasionally, only the top part of the page loads and i get one of the old alert boxes. This alert box, however, doesn't have a message; it is blank. i can click 'ok' or 'cancel', but it does nothing.
I have a few plugins, and had to disable them. I do keep Firebug, however. and web devloper toolbar since I use FF for developing.
I have not noticed this on my PC version of FF.
this error happened with FaceBook once or twice as well, but it happens more with Gmail.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
