  1. For each custom startup application, you will find a .desktop launcher in the folder ~./config/autostart. .config is a hidden folder. Enable "Show hidden Files" to see it in the file manager.

    • In that folder, locate the file for Firefox and open it in a text editor.

    • Find a line starting with Exec=, that specifies the command needed to run firefox. Add the command line options you need to have Firefox launch in Safe Mode, as in

      Exec=firefox -safe-mode %u

    See man firefox for the manual detailing the syntax of the firefox command and its options.
