This is a Mozilla Firefox search plugin for querying the index of
Fedora Core packages at fedoratracker.org. I've submitted it for 
inclusion on the Mycroft page, but it may take some time for it
to show up there. In the meantime, download the two files above
and drop them in /usr/lib/firefox-{version}/searchplugins/.

(Unfortunately, there's currently no way to do this on a per-user
basis.)
