title: Programmatically stop JavaScript execution in Firebug
body: <p>I am currently debugging complex JavaScript code with Firebug. I am looking for a way to stop the JavaScript execution as if it was a breakpoint programmatically.</p>
  
  <p>Example:</p>
  
  <pre><code>instructions ...
  degugger.breakpoint(); // the execution stops here as if a breakpoint was
                         // manually set
  other instructions ...
  </code></pre>
