I am getting a javascript error on startup "Exc in ev handl: TypeError:this.oRoot.enable is not a function"
When I start Firefox, I get an error box labeled [JavaScript Application] with the message "Exc in ev handl: TypeError: this.oRoot.enable is not a function"
I then need to click the OK button before Firefox will start.
This 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).

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 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.

Since updating to Firefox 6.0 I am no longer able to add bookmarks on Yahoo Toolbarl. I receive the following Java Error message: "Exc in ev handl: TypeError: this.oRoot.enable is not a function." When I hit the OK button in the error message it opens up "Add a Bookmark" and when I attempt to add the bookmark there I get this error message: "A problem occured while trying to save the bookmark. Please try again later."
Is this a comparability issue that you are not aware of? Below are the versions of Firefox and Yahoo Toolbar that I currently have installed:
Firefox: 6.0.02
Yahoo Toolbar: 2.4.0.20110815110908
Windows XP, Service Pack 3
I am having this issue on my laptop and desktop. Since I use both computers the Yahoo toolbar has been great for having my bookmarks available on both computers at the same time but no I don't have that feature. I'm told that Google's toolbar also doesn't work either.
Do you guys do any testing or Quality Assurance testing before releasing these versions?Add-ons are the responsibility of their authors. McAfee does not even put their extension on http://addons.mozilla.org you had to install it from their site.
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. -
TypeError: this.oRoot.enable is not a function
This is popping up when I befor I open my browser,in a pop up box under the heading JAVA SCRIPT EXE. What is it, how do I get rid of it?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 -

All details in question. I can provide a copy of an image of the window if needed
Tried disabling all add-ins individually, problem still there. But when I restart via help menu / restart with add-ons disabled, the problem goes away. I do have mcafee installed but the site advisor has been disabled for ages.

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.

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.
