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.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions 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.

In my case it's a list of extensions disabled because they aren't compatible with the new version.They can't be deleted easily,so I will delete Firefox and make a clean install(previous saving bookmarks,profile,sessions,etc)0
Extensions that do not have a "Remove" button are installed by other software and are not under control of the Firefox extension manager.
Extensions installed that way need to be removed via the settings (preferences) in the program that added the extension to Firefox.
I disabled McAfee Site Adivsor and it solved my problem. It is under "add ons" but you can also uninstall it in your control panel but I found it stopped the error message box by just disabling it.
