So, your whole computer freezes? If so, that is not something Firefox can do. If just Firefox is freezing (you can open task manager, etc.), then we could have a problem. But, just create a new profile, and try to reproduce from there, with no changes.
FYI, no freezes with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20090715 Firefox/3.5.1
Severity: blocker → major
Summary: Firefox often bclock whole system → Firefox often block whole system
