// In recent versions of FF the 'beforeunload' event is not fired when the
// window or the tab is closed. It is only fired when we leave the page
// (change URL). If this participant doesn't unload properly, then it
// becomes a ghost for the rest of the participants that stay in the
// conference. Thankfully handling the 'unload' event in addition to the
// 'beforeunload' event seems to garante the execution of the 'unload'
// method at least once.
//
// The 'unload' method can safely be run multiple times, it will actually do
// something only the first time that it's run, so we're don't have to worry
// about browsers that fire both events.
