Today my PC has launched Firefox 3 times on 3 occasions before I could tell my PC to launch McAfee. I shut off Firefox as soon as it would let me and proceeded to McAfee alright. I never use my computer without the antivirus/firewall etc. running even if I am not on the web. I checked Firefox settings but could find nothing specific to my issue. I have not made any changes to Firefox or any other software since the last Firefox upgrade. My PC runs Windows 10. Is there a switch or toggle I can use to ensure my PC waits before loading Firefox? This phenomenon is new today. Thanks!
