[jQuery] load method in FF

[vanches]

Hi,

tried to include .html file in .html file

files structure:
inc_part.html
pages/my_file.html

write in my_file.html

<script type="text/javascript" src="../../../js/jquery-1.3.1.js"></
script>
$(document).ready(function(){
      $("#loader").load('../inc_part.html');
})

<div id="loader"></div>

It works in all browsers, except Firefox 3.5.5
How can I solve the problem?
