Firefox / Firebug JavaScript console.log在某些情况下无法在for循环中使用

Question

There are three lines with console.log in my code here:

JavaScript

window.onload = function()
{//console.log('window.onload');
 var tr = document.getElementsByTagName('table').0].getElementsByTagName('tr');

 for (var i = 0; i < tr.length; i++)
 {
  console.log('i,1 = '+i);

  (function(i)
  {
   console.log('i,2 = '+i);

   if (tr[i].getElementsByTagName('input').length>1)
   {
    tr[i].getElementsByTagName('input')[1].addEventListener('click', function(event) {sessionStorage.hash_self_tr = i;}, false);}})(i);
   }
  }

HTML

<table>
<tr><td>1<input type="checkbox" /></td></tr>
<tr><td>2<input type="checkbox" /></td></tr>
<tr><td>3<input type="checkbox" /></td></tr>
</table>

In Firefox why do the second and third console.log logger not trigger unless I uncomment the first console.log ? This works fine in Chrome.

Answer 1

seem like firebug console is no longer support or update for latest firefox browser.

firefox have it own developer tool coming out no long ago, have all the features firebug have.
