// left-click on restart button: normal restart
// middle-click on restart button: restart + clear caches
// right-click on restart button: no special function

// based on 'Quit' button code by 2002Andreas
// restart code from Classic Theme Restorer add-on
// invalidate caches from Session Saver add-on
