I cleared my browsing history now I can't get into my E-mail. When I try I receive a security box asking for user name and pass word. I click on the enter button, nothing happens. IE works. I removed part of Mozilla and reinstalled it. This did not help.

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.
