Find your profile and delete pluginreg.dat.

And run sfc/scannow and search for missing essential system files.

Hi thanks for the reply.

I've deleted pluginreg.dat and run scannow.

scannow found nothing and firefox still doesn't start.

The error message in Event Viewer is exactly the same as before:-

You can check for malware (i doubt that, unless you got the wrong flash, should check anyways), and look at other solutions.
