Background

Protocols (ex: http, ftp, mailto) are different methods of sending information over the Internet. Protocols may be handled by Mozilla applications themselves, or they may be passed to external applications, or they may not be handled at all. On Linux and Mac systems, this preference determines whether a specific protocol should be handled at all (either internally or externally).
