I get this message when I try to start Firefox after first logging on after turning on the computer.

Have rebooted. Works when Administrator logs in, just does this in my user profile. Have also re-intalled. Mo change in my User account.
 Firefox was working fine for the last 3 1/2 years.  Any suggestions?
