I keep getting "exc in ev handl: Error: Bad NPObject as private data! when I open new browser windows in Firefox 3.6 which I just let the computer upgrade to a couple of days ago. Make this error box go away please!!!!
the error box keeps dinging and I have to x out of it every time I either open a new browser window or try to close others. It's annoying. The only change i made to my computer was that I upgraded to the newest version of Firefox a couple of days ago and that's when it started. Please help me. I can't work like this on my computer having that box come up every time.
It says [JavaScript Application] in the bar and then next to the yellow triangle below it says "Exc in ev handl: Error: Bad NPObject as private data!"
How do I make it go away?

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.
