Firefox started to restrict which ports it can connect to. A Firefox user trying to connect to the Conky by HTTP on the default port would get this message:

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.

With the only option to "Try Again" which wouldn't work.

The workaround is to create a network.security.ports.banned.override key in about:config to list the ports to allow.

We should at least mention this in the documentation.

Ok, I thought Firefox would filter all ports >= some arbitrary value, but it's actually a discrete list, with 10080 happening to be some antique backup software. I suppose the simplest fix would be to just use a different default port :-D
