Can anyone suggest me a good article on preferences.xul ? Presently I
am learning how to just create/modify/acceess preferences through .js
files with no user interface for preferences at all only an image
button on the status bar that will trigger change of preferences,
Should I leave preferences.xul empty if not what should I put ? ( I
dont want any other user interface). Any guidance will be helpful.

Thank you,
hna
