Background

Ports are used when any program accesses the Internet so that the system can keep separate applications' data separate. Some port numbers are reserved for functions such as e-mail or FTP. To prevent potential security risks if a protocol was allowed access a port reserved for a seperate protocol, Gecko applications contain a list of banned ports. This preference allows you to unban a port banned by default and therefore prevent the "Access to the port number given has been disabled for security reasons." or "This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection." messages.
