Firefox extension to close firefox window

Question

I'm developing a firefox extension and i want to be able to close firefox window itself (without any confirm). For example, I want to close firefox window if a specific URL has been loaded. Open/close tab is easy with gBrowser, what about closing firefox window?

Thank you

Answer 1

To quit Firefox

Components
  .classes['@mozilla.org/toolkit/app-startup;1']
  .getService(Components.interfaces.nsIAppStartup)
  .quit(Components.interfaces.nsIAppStartup.eAttemptQuit)

To restart Firefox

var boot = Components.classes["@mozilla.org/toolkit/app-startup;1"].getService(Components.interfaces.nsIAppStartup);
boot.quit(Components.interfaces.nsIAppStartup.eForceQuit|Components.interfaces.nsIAppStartup.eRestart);

Additional Useful Flags

eConsiderQuit : Attempt to quit if all windows are closed.
eAttemptQuit : Try to close all windows, then quit if successful.
eForceQuit : Force all windows to close, then quit.
eRestart : Restart the application after quitting. The application will be restarted with the same profile and an empty command line.

It sounds obvious but you use window.close() to close a XUL window. As to the warning, the best way is probably to temporarily switch the browser.tabs.warnOnClose preference to false . Something like this should work:

Components.utils.import("resource://gre/modules/Services.jsm");

var prefName = "browser.tabs.warnOnClose";
var restorePref = false;
if (Services.prefs.getBoolPref(prefName))
{
  Services.prefs.setBoolPref(prefName, false);
  restorePref = true;
}

window.close();

if (restorePref)
  Services.prefs.setBoolPref(prefName, true);
