Whenever I try to connect to a web site that is running on TCP port 123, Mozilla gives an alert message that reads "Access to the port number given has been disabled for security reasons." It would be nice for any security issues regarding this port (and perhaps others) to be resolved.

We block many known ports : http://lxr.mozilla.org/seamonkey/source/netwerk/base/src/nsIOService.cpp#85 We block this ports because an attacker can redirect from a page to this ports and can manipulate something. If you want to know the exact reasons you should you should read bug 83401 (this bug added the blocking) *** This bug has been marked as a duplicate of 92769 ***
