...
about::config shows that ipv6 is set to false,
so that cannot be the cause. But I will try wireshark.
Thanx,

Hi,
I have a suspicion that you misunderstood ipv6 state in about:config ...
This is what it looks like (assuming it is in an original default state):
about:config
network.dns.disableIPv6 default boolean false
It means that ipv6 is enabled !
If you want to disable ipv6, right click on the line and select Toggle to read
network.dns.disableIPv6 user set boolean true
