Whenever I want to open Firefox or a new window in Firefox, the following error message appears: [JavaScript Application] Exc in ev handl: TypeError: this.oRoot.enable is not a function. How can I solve this?
A little window with the error message pops up each time I wnat to open Firefox or if Firefox wants to open a window. I have to click the OK button and then Firefox opens. This is annoying.

That problem is caused by McAfee Site Advisor
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode 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.

Did you try to start Firefox in Save mode to see if another extension is causing it?
