      What you need for IPv6 to be enabled in FF is

network.dns.disableIPv6     default boolean false

That means that FF *will* use AAAA records and therefore try IPv6.

If you flip it to true, FF will not use AAAA records and will only
try IPv4.

Thanks for all replies.
The issue was simple (as always) but I will post this in case others come across
similar problems.
In Firefox "about:config",  disable ipv6, and then ipv6 will work.
Strange, but true, and would appear to be one of "those" programming errors.
Or someone with a perverse sense of humour.

Hi Alan,
Do you have ipv6 enabled on your computer?
www.fx.net.nz is ipv6 enabled, and I suspect if the website is loading
slowly it may have to do with faulty v6 transit.
(ie, if you are accessing it over a tunnel going via the US or EU)
You could try www2.fx.net.nz which will go to the same place, but does not
have a v6 DNS record.
We haven't had any DoS attacks this evening that I'm aware of.

My apologies for this (my first) post.
As a former Sys Admin, I retain an interest in this area
for purely personal & academic reasons.
After observing the post, I attempted to access http://www.fx.net.nz/
and it timed out.
And is doing so again this evening.
Your thoughts?
All else is functioning fine. ( I run PClos linux on my desktop & use Open
DNS)
