Please test this in Firefox's safe mode, this sounds like a problem caused by an
extension

This is an extension issue, I suggest disabling a few of your extensions at a time to narrow it down and then notifying the extension author.

The Mozillazine forums or IRC chat can help you further http://www.mozilla.org/support
