Thanks, Dave.  Yes, I noted that the port 443 was /not/ the one associated 
with the http:// URL, but I did cut and paste the URL from your message, 
and there was no "https" in it.  I simply reported what i saw.  I just 
tried it again and did /not/ get the warning, however on closing and 
re-opening Firefox, the warning has appeared with the same, non-https, 
URL.  I suspect that it comes from Firefox looking ahead to the other 
links on that page, some of which are https.

Yes, in the past this issue has arisen, and I may have clicked "OK" if 
Internet Explorer gave such an option for that URL.

It makes it difficult to take an discussion about "security" issues 
seriously when ntp.org can't even get a "accepted" certificate.
