Thanks to the people over at undergroundmedia.org, we have a Firefox/Mozilla search bookmarklet.

Install Podfeeder Search bookmarklet
Click 'Ok' when prompted to verify that you wish to install the search engine.

A search plug-in allows you to search the Podfeeder directory from your browser without actually having to go to our site first.

Technically, a search plug-in is a text file and an image file that will be installed into your Firefox or Mozilla install directory under searchplugins/. There you will find podfeeder.src and podfeeder.png.
