title: Firebug doesn't load JavaScript files or stop execution on breakpoints
body: <p>I'm new to Firebug and having a lot of trouble.</p>
  
  <ol>
  <li>JavaScript files usually show up empty, or load partially (some of the time)</li>
  <li>Lines are not available to set breakpoints on frequently (line numbers are greyed out)</li>
  <li>When I do set breakpoints, script execution often does not stop on them</li>
  </ol>
  
  <p>I'm using Firebug 1.3.3 and Firefox 3.0.11. I have disabled all other Add-ons. I'm loading Javascript from localhost. Sometimes closing the window and re-opening the page I was on clears things up, but that never lasts for more than a couple page loads.</p>
  
  <p>I'm working on learning jQuery, which obviously has a huge library, but I imagine many other people use Firebug for the same, so that shouldn't be a problem. Also, most of the time (but not always), Firefox loads and executes the JavaScript no problem; just Firebug can't see it.</p>
  
  <p>Due diligence:</p>
  
  <p>These discussions seem to cover the same problem, but have no answers:</p>
