title: How to make javascript debugger enable in firefox
body: <p>Say you have javascript code sample like below in asp.net page body onload event. </p>
  
  <pre><code>function OnloadHandler()
  {
      ...
      debugger;
      ...
  }
  </code></pre>
  
  <p>We know when run this in IE ,the <code>debugger</code> just like a break-point , and wait for us to debug . But when I run it in Firefox . The code <code>debugger;</code> didn't work. I had to manually to set a break-point with Firebug.
  Can anyone tell me how to make <code>debugger</code> enabled in Firefox? thanks.</p>
