Answer 1

You can use my sysend.js library, it use localStorage to send messages between open tabs/windows. All to do is this code:

sysend.on('notification', function() {
   sysend.broadcast('multiple');
});
sysend.on('multiple', function() {
   // this will fire n-1 times if there are n tabs open if n > 1
   alert('multiple pages');
});
sysend.broadcast('notification');
