Kiosk mode for Firefox

1. Full screen mode
2. Reload the page by updating the external file.
3. Bidirectional message channel between JavaScript UI app and native Python app

Firefox will start in full-screen mode. Press F11 in order to exit full-screen mode. Context menu: biKiosk -> Full Screnn - will return kiosk into full screen mode again.

May be add-on is not enough for full full-screen. It may be nessesary some additional steps:

1. Install the Gnome Shell Integration Add-on (by Yuri Konotopov) and add "disable all gestures" extension to the Gnome
2. Add some additional css rules from https://github.com/MrOtherGuy/firefox-csshacks to the chrome file
   • hide tabs
   • autohide main toolbar
   • etc...
3. Go to about:config page ane set:
   • browser.sessionstore.resume_from_crash = false
   • security.insecure_field_warning.contextual.enabled=false
   • security.fileuri.strict_origin_policy = false

Copy files bikiosk.json and bikiosk.py into the ~/.mozilla/native-messaging-hosts directory. Create it if does not exist.

Eddit bikiosk.json, fix path , it must contain full path to the file: bikiosk.py.

Edit bikiosk.py. Variable path must points to the file which will be whatced by Add-on.

Install tailer by pip install tailer command.

Add-on runs tail command. It gets the last line when the file was updated and pass this line to the JS application. Currently only one comand realised: Reload. It reloads active Firefox Page. Due to tail command limitations you must add "command" to the end of file and terminate it by carriage return.
