There were kinds of message as follow, "Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function." or another message such, "Exc in ev handl: Error: Bad NPObject as private data!" How to solve those?

When open Firefox to surf in internet, those messages always appear.

I occasionally get error messages popping up when I run Firefox 7. The messages often say "Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function". does anyone know how to fix this?

After I downloaded and installed the latest version of Firefox, I started getting these error messages every so often when I launched the browser. These messages will usually pop up every third time or so I open the browser and pop up on every page, sometimes multiple times, and I have to clear them away before I can do anything on the page. The message usually reads "Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function". Is there any thing we can do to fix this?

I continuously am receiving this pop-up, "Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function." What is wrong and how can I fix it?

I was receiving a lot of trash emails and such and cleared all my cookies and history. Now I am getting this pop-up and it is interferring with my internet usage, "Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function." What is it and how can it be fixed, deleted, gotten rid of, etc. Thank you

Hi. SiteAdvisor is usually located in Firefox's add ons extensions. Hope this helps.

Why do I get this warning with every new web page: Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function?

Uploaded 6.0.2 and now I get a Java script error message with each new page I access: "Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function" . Browser is working ok, but this message is a pain. What can I do?

I had this problem for a long, long time. Today I discovered if I went to Tools, Options, Enable Javascript, Advanced and deselected "Hide the Status Bar" the problem went away.
It is worth a try. Worked for me.

I keep getting this message whenever I open a new screen - Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function - How do I get rid of it and STOP it?

I've told you the problem and I'm getting pretty irritated that it came on all of a sudden and I can't figure out why. HELP!

Why do I get the following error msg's: (1) Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function (2) Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function (3) 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.

Since upgrading, I keep getting a pop-up box which says "Exc in ev hl: TandypeError: oSAPlg.oRoot.log is not a function" What does this mean and how do I get rid of it? Thanks in advance for your help! in English

The pop-up box starts when I use firefox and it keeps popping up every time a page changes or every time I do anything in Firefox. I press "okay" and multiple boxes with the same message pop-up. Again, thanks!

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.

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

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"

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.
