I've tried setting some settings to false like toolkit.winRegisterApplicationRestart & browser.startup.windowsLaunchOnLogin.disableLaunchOnLoginPrompt and this worked for a while and now it's back to starting with windows.

Hi everyone, I'm desperately trying to disable Firefox from starting when my windows starts up. I've tried disabling startup apps. I've tried setting some settings to false like toolkit.winRegisterApplicationRestart & browser.startup.windowsLaunchOnLogin.disableLaunchOnLoginPrompt and this worked for a while and now it's back to starting with windows. The box is unticked in menu - settings - Open Firefox automatically when your computer starts up. I tried al-sorts of things but I'm still having the same problem Does anyone have any possible solutions I can try please? At the moment I have a script to end task as I can't find any other solution. windows 11 24h2 firefox 132.02
