jQuery Forum

 Just tested, and it doesn't work with 1.3.2 either. Here's the xul snippet I tried:

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<wizard id="yourwindow" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<wizardpage value="Put your XUL here!"/>
</wizard>

You can actually play with that on http://ted.mielczarek.org/code/mozilla/xuledit/xuledit.xul
