title: TypeError: asm.js type error: Disabled by debugger
body: <p>I'm trying to run a asm.js code in Firefox 29 but I get this warning from debugger console:</p>
  
  <pre><code>TypeError: asm.js type error: Disabled by debugger
  </code></pre>
  
  <p>Here is the code:</p>
  
  <pre><code>function boo() {
      "use asm";
  
      var result = 0;
      for (var i = 0; i &lt; 1000000000; i = (i + 1) | 0) {
          var result = result + i | 0;
      }
  }
  </code></pre>
  
  <p>It seems the asm.js is disable when I work with it, How can I fix this issue? </p>
