Paste the following in for firefox

# Disable screen blanking and power management (works on both X11 and Wayland via xwayland compatibility)

xset s off
xset -dpms

# Hide mouse cursor (unclutter works best on X11; if you're on pure Wayland, see notes below)
unclutter -idle 0.5 -root &

# Optional: Clean any crash flags (Firefox is more forgiving, but harmless to keep)
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.mozilla/firefox/*.default*/prefs.js 2>/dev/null || true

# Launch Firefox in kiosk mode
# -kiosk          → Fullscreen kiosk (hides UI, prevents exiting easily)
/usr/bin/firefox --kiosk --private-window https://synology.onling.com/webman/3rdparty/SurveillanceStation/login.cgi?SynoToken=nQhMc44EQyoEpeg &

# Optional: Cycle tabs / refresh every 10 seconds (your original behavior)
# If you only have one URL, you can comment this out or change it to a refresh instead
while true; do
    # Send Ctrl+Tab to cycle tabs (if you open multiple tabs)
    xdotool keydown ctrl+Tab; xdotool keyup ctrl+Tab;
    sleep 10

Make it executable

sudo chmod 777 /home/pi/kiosk.sh

Make a service file to auto startup

Paste the following in

[Unit]
