There are several ways to find software available for FreeBSD.
The FreshPorts website tracks changes to the third party applications in the ports tree as they occur. Users of the Firefox web browser can install a search engine to be able to search through http://www.freshports.org/ and find software available for FreeBSD on a friendly manner.
To do so point to http://www.searchplugins.net/pluginlist.aspx?q=freshports&mode=title and click to install the search engine. After installing it go to Firefox's search box where Google's engine usually sits and choose the newly installed FreshPorts search engine.
By doing so you can search for applications to install on FreeBSD from the comfort of Firefox.
