Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this. When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status. Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?
