Since I reinstalled my Windows 10 laptop, Firefox 58 or higher won't launch. Firefox 57 or lower starts fine. But when I install FF 58+ and start the program, nothing happens. The cursor changes briefly and after a couple of seconds there's no more activity. The firefox.exe process shows no more activity.
What I tried: - Installed FF 58 or higher and started the program. No luck. - Started in safe mode, or profile manager. No luck, nothing happens. - I deleted all firefox files/registry keys (also from %appdata% and %localappdata%, as well as all reg keys below HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla and HKEY_CURRENT_USER\Software\Mozilla. No luck. - With ccleaner I cleaned up all temp folders. No luck. - I temporary disabled a/v software (Windows defender and Palo Alto Traps). No luck. - I was running Windows 10 1607. I upgraded to 1709, but still no luck. - I analysed the process firefox.exe with process monitor from sysinternals. I don't see anything weird and after a couple of seconds, the process finishes with exiting a thread, and that's it. No more activity from this process, until I kill it manually. The process monitor log doesn't show any activities in accessing the user profile settings. - When I install FF 57 everything works fine. Then when I choose to upgrade, the upgrade finishes but FF won't start anymore. - I can't find any log files explaining what's going on. - Before I reinstalled my laptop, I used the same image (sccm) 1 year ago, and firefox was working fine then. - Finally I also looked at other toolings which could interfere, such as VLC media player. I removed those tools as well. No luck.
I'm at a loss here. Can somebody point me to the right direction? Perhaps version 58+ introduced something completely new which somehow causes issues with my installation? Any log files I'm missing, which might explain what's going on?
