That may be caused by security software. ESET was a recent culprit. You have to disable the software or add mozilla. org to its trusted list. Updating the security software may also fix the issue.

i don't use any antivirus or security programs, i have also tried uninstalling and reinstalling firefox, still no fix. i checked windows firewall, firefox is allowed to go through.
