inputs selector problem in Firefox

inputs selector problem in Firefox

Hi,

I have form like following:

<form id="form1">
<div id="one">
<input id="input1" type="text" />
<input id="input2" type="text" />
</div>
<div id="two">
<table>
  <tr><td>
    <input id="input3" type="text" />
    <input id="input4" type="text" />
  </td></tr>
</table>
</div>
</form>


and JS code:
$('#two > *').attr('disabled', 'disabled');


and it's not disabling the inputs 3 and 4 in FF, but it works perfect in IE.
What am I doing wrong?

Thanks in advance
