title: How to detect left click anywhere on the document using jQuery?
body: <p>I have this right now:</p>
  
  <pre><code>$(document).click(function(e) { alert('clicked'); });
  </code></pre>
  
  <p>In Firefox, this event is firing when I left-click OR right-click. I only want it to fire when I left-click.</p>
  
  <p>Does attaching a click handler to the document work differently than attaching it to other elements? For other elements, it only seems to fire on left clicks.</p>
  
  <p>Is there a way to detect <em>only</em> left clicks besides looking at e.button, which is browser-dependent?</p>
  
  <p>Thanks</p>
