Started to crash Firefox 3.5.1 reproductively when loading most sites. This is strange, as the error even resides after disabling all other Addons, but just recently appeared today after using both FF 3.5.1 and Ff/Rew-Buttons for some time now.
E.g. addons.mozilla.org/ does not cause the browser to crash, however most sites do. One of the easiest: http://hidden50.hi.funpic.de/
I will post this report on the addon's homepage, too.
