Yesterday when I started Firefox it ask/recommended an immediate update. I complied and now Firefox crashes as soon as I try to start it. I will not start in safemode. I tried uninstalling Firefox 43 and installing a previous version. It now crashes as soon as I try to start it.

System is Windows 7 with an I7 processor.

Hi Ken.

Your description seems to fit to a known issue when running Firefox 43 on a computer where G Data security software is installed. If it's your case, please read "Firefox 43.0.3 startup crash with G DATA security software" help article.

You can check in the the Windows Control Panel if you can find "NVIDIA Network Access Manager" or "NVIDIA ForceWare Network Access Manager" and uninstall this software.
