Answer 1

Ok I found this solution:

First we must in about:config setting this:

1) signed.applets.codebase_principal_support" to true to allow the execution of

 netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserWrite');

and to show the user a confirmation window to allow that execution

2) "dom.disable_window_open_feature.location" to false to allow to hide the location bar

3) "dom.disable_window_open_feature.status" to false' to allow to hide the status bar

So code like this will put Firefox in a real full screen:

window.onload = function() {

    netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserWrite');
    var newWin = window.open('http://www.stackoverflow.com', 'so', 'dialog=yes,minimizable=no,personalbar=no, directories=no, titlebar=no, location=no');
}; 

After in the LAN we should set for the clients that about:config preferences and we can use a remote tool like suggested by SpliFF.

I think UniversalBrowserWrite can only be set if the call comes from a chrome window which has itself a chrome window as parent

Maybe the R-kiosk addon does the right thing for you
