I keep getting this Exc in ev handl: TypeError: this.oRoot.enable is not a function; how do I fix this, i have re-installed this twice. are you offering a patch or anything?

After I installed an update yesterday, I keep getting the above error notice, do you have a patch?

That problem is probably caused by McAfee Site Advisor

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?

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.
 Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it.

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.

Why do I get the following msg's on startup start Firefox? (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!

I get the following msg's. This happening more often, and when I back out to restart it may take a couple of times so that I do not get the error msg's?
Exc in ev handl: TypeError: oSAPlg.oRoot.log is not a function
Exc in ev handl: Error: Bad NPObject as private data!

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 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.

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.

Other than moving to Version 4 or 5, neither of which support Java which I need, is there a way to fix the "Exc in ev handl: TypeError: this.oRoot.enable is not a function" bug I am getting in version 3.6.23?

I have used Version 4 and 5 and unfortunately neither supports Java functions that I require. I like the look and feel of 3.6.23 but there seems to be a script error on startup of Mozilla. When I double click the Icon to open the program I get "'''Exc in ev handl: TypeError: this.oRoot.enable is not a function'''" and so far haven't been able to locate the code line to fix it. I would rather not reverse Engineer the program.

The following keeps popping up before firefox will load, Exc in ev handl: TypeError: this.oRoot.enable is not a function

There is a pop up box, it says,"Exc in ev handl: TypeError: this.oRoot.enable is not a function" It pops up before Firefox will load, what is it?

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.

I am getting an Exc in ev handl: TypeError: brw is undefined. This only happens in firefox. Chrome or IE is not affected.

When I open or request a page by clicking on a link I get the Exc in ev handl: TypeError: brw is undefined message every time. Until I click on the ok button the page will not open. I also now have to copy and paste page addresses almost every time I open a new firefox page. This is not happening with other browsers.

Get error: "[Java Script Application] Exc in ev handl: TypeError: this.oRoot.enable is not a function"--huh?

This error is received a LOT (but not every time) when I try to select a link. This only started happening in the last few days. It's always received when I'm initially signing on. If I hit cancel or okay (there's only one option, I forget right now the exact wording) USUALLY the action then proceeds as I'd expect. But sometimes I'm presented with an incomplete web page.

I did it in my computer, but I can not uninstall the Site Advisor alone. I need to uninstsll the the total McAfee plus. What should I do?
But another user in my computer they do not have this problem. If I try to use IE or Chrome etc , I can not find this problem. I use firefox since 2006 and do not want to change another one. What should I do?
By the way I have this problem after I update Firefox6 3 weeks ago and always allow 1 plugin work. The other user in this computer they just allow firefox plugin working 1 times.
It will pop out if I disable the siteadivsor.
many thanks
