I've checked the "Startup" on my laptop and Mozilla nor Firefox are listed, yet Firefox still opens whenever the computer starts up. I even close down Firefox before shutting down the laptop. Help please :)

Hello terryflorida4,

Would you please type in the address bar :

about:config and press Enter (ignore the warning)

Type in the search bar toolkit.winRegisterApplicationRestart

and set its value to false.
