AJAX call not working in FireFox but works on everything els

Can somebody take a look at this...

http://www.churchboom.com/index1.asp

The white my notes section on the bottom left is a div area that is loaded with an Jquery Ajax call just like 2 other areas on the page. This works fine in IE, Safari (PC), Chrome but not in Firefox. It just shows blank white.

Any ideas?
