title: console.log not showing in my firebug
body: <p>In <a href="http://jsfiddle.net/T9AYR/" rel="noreferrer">jsfiddle.net</a>, I have this simple code:</p>
  
  <pre><code>console.log('yep');
  alert('hello');
  </code></pre>
  
  <p>I can see the alert window but nothing in my <code>firebug</code> console.</p>
  
  <p>Is there a reason why ?</p>
