I had some problems getting Firefox to accept/provide arguments to a protocol handler command entered in the about:config page [see
previous post for about:config settings], but I have found a workaround, and posted a HOWTO document about it. See:
HOWTO Enable Telnet URI Handling in Firefox.
The gripe here is that telnet://host.name:portnum/ URLs didn't work by default in Firefox. The HOWTO gives a fix.
