We have an Ubuntu computer that opens Firefox in Kiosk mode automatically when the computer boots. This computer is connected to a TV and is used as an informational dashboard. No user interaction is required, so no keyboard or mouse is connected. Every so often, Firefox updates (among other updates) and the computer reboots overnight. When booting after a Firefox update, it shows a "thank you for loving firefox" message instead of the specified URL. The easiest fix is to hold the power button and manually reboot when this happens since there is no keyboard and it's quicker than logging in via SSH. Is there a way to prevent this message from showing after updating? We want to keep the automatic updater enabled to keep it up to date, but this is not desirable behavior.
