Unsurprisingly, this website uses e4x (and also doesn't work in Chrome):

var sp =
<searchlist>
	<provider group="1" name="Google">
		<image>google.png</image>
		<query type="web">http://www.google.com/search?q=</query>
	</provider>
....
</searchlist>;

Does it also not work in IE?

Nope, doesn't work in IE, Safari and Opera. View Source shows the same e4x code in all browsers.

Closing then. Thanks for bisecting this and filing a bug report, but unfortunately this website depends on a FF-only feature that is on its way out. See this page for more information:

Have we contacted the site authors?  We should send mail if we can find an address, at the least...
