Since I upgraded my firefox..I get this box most of the time when I click on a link to go to another page...
Java Script
Exc in ev handl: Error: Bad NPObject as private data! Then I have to click ok to get the page to open.
That issue can be caused by the McAfee Site Advisor extension

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

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"

I like to work with about 6 tabs open on Firefox and typically this has been absolutely fine. Starting around November 2011 each time I have multiple tabs open when I open a new gmail message, or open an order or any other action within an open page a message pops up that reads
Exc in ev handl: Error: Bad NPObject as private data!
then that site immediately opens in a new browser window.
I do not have this issue with Google Chrome or Internet Explorer but I would rather use Firefox. I ran McAfee an extra time thinking it might be a virus but that did not help. Any ideas?That issue can be caused by the McAfee Site Advisor extension

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).

Okay, I will have a window open with 4 tabs open. At first, everything is fine, but after a day or so, a message will pop up on screen saying "'''Exc in ev handl: Error: Bad NPObject as private data!'''" and after you close it out, the tab you were on will close and reopen in it's own window. I then have to shut down all both old and new windows and open a new window with my original 4 tabs again. It will work fine until a few days pass and it starts over again.

In the past few days I have been getting the following popup when I use firefox as my browser: Exc in ev handl: Error: Bad NPObject as private data!
I assume it came from your latest update. I have windows vista with a 64 bit processor, and I am using the latest version of firefox. I checked to see if I was getting the same error message with explorer and I am not. It appears to be some sort of conflict with java script. Can this be corrected?re: recommendation -- "Remove McAfee Site Advisor and other extensions/plugins reported in the following lists of Blocked/Problematic extension: "
NO -- I use it to protect my surfing! Why must FireFox insist on constantly breaking 3-rd party vendor apps!?! Even IE doesn't do this.
For all the ballyhoo about FF and how great it is -- it ISN'T when it comes to how it supports other companies apps. (RealPlayer, Google, McAfee, etc.)
Shame on them. I shouldn't have to give up functionality, and in this case protection -- just to use FF -

When I use facebook, I keep getting this message [Java Script Application] Error: options is undefined whenever I try to return something, click on a link, or message, open a game, etc. ... I have Windows 7, addons of greasemonkey and better facebook (which seems to have disappeared)

http://www.facebook.com/reqs.php#!/?ref=homeStart Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
