Every time FF4.0.1 is opened the error message shows and must nbe closed before the FF screen shows. I've reloaded FF4.0.1 in hopes some code was missing, but no change....the Java Script Application error message still shows?

Following the ideas in the prior FAQ cited, went to the FF Troubleshooting extensions and themes & followed it down through disabling extensions. The Ask toolbar turned out to be the culprit even though in was not on the FF screen.

I noticed you have My Web Search installed which might also cause you problems at some time in the future. I'd avise you to disable that too via Add-ons | Plugins. See http://en.wikipedia.org/wiki/My_web_search

You also need to update Flash via http://get.adobe.com/flashplayer/ Details of the vulnerability in the version you have installed at the moment can be seen here: http://www.adobe.com/support/security/advisories/apsa11-02.html
