Please see solution in http://kb.mozillazine.org/Problematic_extensions for "McAfee Site Advisor".

(Windows): For best results you should uninstall McAfee Site Advisor from Control Panel > add/change programs (Programs and Features). Reboot the system. Then Reinstall from http://www.siteadvisor.com/ and reboot the system. When installing refuse other suggested (crapware) applications.
