I have a disc which uses my browser to display the disc contents (without going on the web) Firefox says it

"This address is restricted

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has cancelled the request for your protection."

How do I permit the use of that port?

I use 3.6.10 on XP
