Mozilla said five of the eight vulnerabilities were 'critical', meaning an attacker could exploit the weaknesses to run malicious code on the compromised machine. Seven vulnerability updates have been issued for the previous version of Firefox, version 1.5, of which five are rated as critical. Mozilla also urged users of its Thunderbird email application to download several security updates.

Mozilla's Release Notes [mozilla.com]
If you've never done a clean install since Firefox/1.5 or 1.x, then do so now. Remove Firefox and reinstall it. Your preferences and bookmarks should be preserved, but copy/save your entire profile directory just in case.
It's also possible you may have leftovers from an incompatible extension, so reinstall updated extensions one-at-a-time after reinstalling Firefox and test each one.
You can also start Firefox in "Safe Mode" from the Windows Start->All Programs menu -- Look for the safe mode option. This will disable all extensions so you can determine a bad extension from a bad base Firefox install.

It turned out that SearchStatus 1.18, which is one of my favorite add ons, was the culprit. I have been having problems since the 2.0.0.1 update, and it's all better with this one disabled.
