Thanks in advance for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.

Make sure that you update each program to get the latest version of their databases before doing a scan.

I methodically went through all of the suggested checks you suggested; even loading new security software that you listed. At best, the microsoft product found three java exploits that I removed or quarantined.

But after the last reboot, the same message came up on screen almost immediately. Admittedly, it is not now happening as often but it is early in my experience to say that it is at an acceptable level of annoyance.

FYI, it did seem to run unaffected in the safe mode but I can not run it continuously that way, can I? I only did it for less than an hour. What does it mean if it were to run best in the safe mode?

My only real insight is that as I started opening up my home page, I immediately went somewhere else before it had stopped loading that first page. Should that in some way produce the problem? I don't ever remember having to wait to load one page before going somewhere else.

Any other suggestions? Thanks.
