Doesn't work in FF 4 beta on Windows XP Puntuado con 1 de 5 estrellas

On Windows XP for Firefox 4, this add-on doesn't work at all. I have menus turned off and it shrinks the Firefox Application menu so small that it's not clickable and makes it so the window can't be dragged. I had to uninstall the add-on to regain control of the browser. That was in a new profile so it's not an add-on conflict.

Resolved that issue with version 1.6.5 in Sandbox or on my Website. Thanks for reporting the problem.
