[jQuery] ui-accordion page is not working in Firefox

[al...@ourlaughingplace.com]

I have a page using UI-Accordion which has been up for a few months.
I just discovered that it is not working right on firefox 3.5.5, the
entire accordion is compressed into one fat line.  This page works
fine in all other browsers, Chrome, IE8, IE6, Safari 4, Opera.  I have
other pages on same website which use ui-accordion and they work fine
in Firefox, using the same jQuery file set.

Here is a link to the page:  http://www.ourlaughingplace.com/aspx/dining.aspx

This is an asp.net, C# code.  Accordion code looks like this, content
is filled in by back end script:

<div id="accordion" style="width:580px">
