Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

Change the default browser to something other than Firefox and see if that changes which browser is launched at startup.

Do a full system scan for malware with something like Malwarebytes.
