Firefox 57, Firefox Won't Start

more options

Just is case someone was having the same issue. If Firefox won't start, not even in (Firefox) Safe Mode, with no error message. But when Windows 10 was started in Safe Mode, Firefox will run normally. If you are running Logitech Web Cam Software, uninstall it to see if that solves your problem. It did for me. It took me several hours of troubleshooting to figure this out. Maybe this info. will help someone else.

Thank you for posting this.

The Logitech camera problem first emerged with Firefox 56.0.1 when 32-bit Firefox users were auto-migrated to 64-bit Firefox. Apparently there was no conflict with the 32-bit camera software, only the 64-bit camera software.

Some users reported back that there is newer software available from Logitech that allowed them to reinstall the camera. But if you don't use it, then... you're done.
