Windows – Firefox Quantum – Kiosk Mode

I currently use this method to emulate chrome's kiosk-mode in Firefox Quantum on Windows 10:

1. Install Firefox Quantum
2. Install AddOn AutoFullscreen
3. in Firefox's address-bar, type about:config and set the parameters zoom.maxPercent & zoom.minPercent to 100 (hence, disabling zoom)

4. CREATE Folder/File "C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>.default\chrome\userChrome.css" with the following content:

   @namespace 
   url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
   #fullscr-toggler { display:none!important; }
   

5. Disable all System-Notifications in Windows 10

6. Disable (if possible) all System-Touch-Gestures to disable all Windows 10 Bars and Menus by going to the Local Policy Editor -> Computer Configuration/Administrative Templates/Windows Components/Edge UI and disable allow edge swipe

It would be interesting to know if there are better/easier alternatives ways to achieve the same.
