I saw this answer https://support.mozilla.org/en-US/questions/1303747 but I don't understand anything from it, English is not my first language. Will I lose my bookmarks and extensions? Do I delete the folders in program files or run the uninstaller? When running the installer there is an option to "restore default settings, remove extensions etc", should it be on or off?
I deleted the folder, ran the installer again and set the option to restore default settings off, and still can't open firefox. Can someone explain in simple terms?
