What will get rid of "EXC in EV handl: error bad NP object as private data"?

I am taking some online classes and whenever I am trying to do homework or send in my assignments or take a test this error report comes up: EXC in EV handl: error bad NP object as private data. What does this mean and how do I get rid of it? I need to be able to do my college work online and know that it is getting to the instructor. How can I know if my assignments and test and any other communication with my college are getting to the right place?

  • 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).

  • Exc in ev handl: Error: Bad NPObject as private data! How do I ge rid of this?

    Exc in ev handl: Error: Bad NPObject as private data! I get this error when opening and closing tabs. It only happens when using Firefox. I am running 7.0.1 on a 64 bit version of windows. While researching this problem I discovered thousands of people have the problem. This just started recently. No real fixes or causes have been found. One solution listed was to disable McAfee site adviser which I use and have no plans to remove. I really like Firefox but if I must choose between it and Site adviser I'll have to switch to another browser.

  • A message will pop up (Exc in ev handl: Error: Bad NPObject as private data!) and the tab I was on will close out and reopen in a new window. Why is it happening and how do I stop it?

    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.

  • After updating Firefox I am getting this message any time I do anything "Exc in ev handl:Error: Bad NPObject as private data"

    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 am gettng the following popup when using firfox as my browser: Exc in ev handl: Error: Bad NPObject as private data!

    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

  • Can anyone fix this issue? It is both on my home and office computer anf from online blogs it seems to be a large problem for many. Exc in ev handl: Error: Bad NPObject as private data!

    Exc in ev handl: Error: Bad NPObject as private data!

    Disable "McAfee Site Advisor" extension which was just updated to 3.4.0, which probably took it out of the addons block list.
    * "Ctrl+Shift+A" > find McAfee Site Advisor and use "Disable", and then restart Firefox.
    * Do a Google Search no problem
    * It seems that if you re-enable Site Advisor again, and restart Firefox you are okay. At least you know where to look if you get the error again or Google searches slow down.
