I don´t get any Java Script referral on the: Exc in ev handl: Error: Bad NPObject as private data, what is then my problem?
Exc in ev handl: Error: Bad NPObject as private data
This is the pop up that keeps annoying me in FF. You send me the question: The box that the error is in says something about JavaScript?
I´m answering NO!
This issue can be caused by an extension that isn't working properly (McAfee Site Advisor).

This error happens each time I use Mozilla. especially when I click on an extension or try to work in any of my e-mail accounts (Yahoo, Gmail, or RCN). Sometimes I am able to continue by just clicking OK and other times it prevents me from completing my task. This started happening right after I downloaded and installed your latest version of Firefox. I see others are having the same problem. Error message is "Exc in ev handl:Error: Bad NPObject as private data"

it is happening more and more often when I start Firefox, and it takes up to four times of restarting to stop getting the error msg's.
this does not do any good if it is not reviewed by a staff Tech.

It's a Java Scrip error window......
Try the Firefox SafeMode to see how it works there. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
* You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
''Don't select anything right now, just use "Continue in SafeMode."''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

The information in the question window is pretty complete. I did go in and check my latest version of Java and it is Java 6 Update 21, installed in July of this year.

This error message recently started popping up periodically on web pages that seem to have graphics or photos. There have been recent Adobe updates, but I can't verify which ones and whether they are the issue. On the other hand a recent Firefox update 7.0.1 indicated it was incompatible with a number of plug-ins? Could that be the source. Incidentally after I receive the message: it comes on twice, I am returned to a previous screen without further problem.

that's about it!
McAfee Site Advisor 3.4.0 just came out of the addons blocklist, and you have SiteAdvisor and even though that is the current; nevertheless, you should uninstall it and reinstall it as noted in https://community.mcafee.com/message/203466 for a fresh version with only current files.
Also refer to http://kb.mozillazine.org/Problematic_extensions relating to McAfee Site Advisor 3.4.0 for more specific instructions.

This was the answer. Thank you so much for the easy to follow instruction you left for me.
