autocompleter not working in Firefox 5 Mobile

[jdee]

The entire QUnit test suite passes in that browser, but anything typed into the autocompleter does not work. That applies to the main site as well. That is, if you visit either of these URLS in Firefox 5 Mobile:

http://m.dubsar-dictionary.com/m
http://dubsar-dictionary.com

And type something into the search box on either page, you will not get any autocompleter suggestions. This could be due to an issue with jQuery UI in the Firefox 5 Mobile browser. It could also be a quirk of the recent separation of routes into different domains. However, if it were the latter, it would not likely be limited to one browser. Autocompletion works quite well in Mobile Safari on Android 2.2.1 and in the Apple iOS Simulator on OS X.
