title: In Firefox, console.log is not showing anything
body: <p>I'm trying a simple console.log function in Firefox:</p>
  <pre><code>console.log(&quot;Hello, World!&quot;);
  </code></pre>
  <p>You may try it on: <a href="http://jsfiddle.net/EkZjK/" rel="noreferrer">http://jsfiddle.net/EkZjK/</a></p>
  <p>You may also try the full code in a stand-alone HTML file:</p>
  <pre><code>&lt;html&gt;
      &lt;head&gt;
          &lt;meta content=&quot;text/html;charset=utf-8&quot; http-equiv=&quot;Content-Type&quot;&gt;
          &lt;script type=&quot;text/javascript&quot;&gt;
              console.log(&quot;Hello World !&quot;);
          &lt;/script&gt;
      &lt;/head&gt;
  &lt;/html&gt;
  </code></pre>
  <p>I get console logs in Chrome. 
  But in Firefox I cannot see the logs.</p>
  <p>I tried the <a href="https://en.wikipedia.org/wiki/Firebug_%28software%29" rel="noreferrer">Firebug</a> console and <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>J</kbd>.
  Both don't show the log message in Firefox.</p>
  <p>PS: I restarted Firefox, restarted Windows, tried on another machine, deleted the Firefox profile and created another one, and reinstalled Firefox. But the problem still exists.</p>
  <p>How can I solve this?</p>
