Thread:Project:Support desk/Search autosuggest broken with Firefox 9

I upgraded by browser the other day, and autosuggest in the search bar on my wiki now no longer works. I looked around for info on this, and haven't found anything. My first shot was to upgrade to 1.18.1; that didn't resolve it. I'm using PHP 5.2.17 and MySQL 5.0. The url is http://www.jonfmorse.com/wiki

Ideas?
