title: How to make firefox report the javascript error?
body: <p>I am developing with Firefox and Firebug, but in my environment if the js has the syntax error, the firefox will not report any error, it just stops there.</p>
  
  <p>Then I have to use IE to reload the page, IE will report the error at the bottom left corner, and after clicking it I can see the line number of the js error.</p>
  
  <p>I am wondering if I misconfigured something? I think at least firebug should report the error as IE does. But firebug displayed nothing.</p>
  
  <p>The example code(show error in IE but normal in FF):</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
    &lt;style&gt;
    body { color:blue; }
    &lt;/style&gt;
    &lt;script src="http://code.jquery.com/jquery-1.4.4.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;script&gt;
      if (a &lt; ) 0 {
      }
  
  &lt;/script&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
