this is because of Mozilla's internal coding mistake.
if Mozilla is compiled with IPv6 support, it will do:
hp = gethostbyname2(host, AF_INET6);
hp = gethostbyname2(host, AF_INET);
for host lookup. It means:
- if the destination host is IPv6 only, IPv6 addresses will be tried.
- if the destination host is IPv4 only, IPv4 addresses will be tried.
- if the destination host is IPv4/v6 dual stack, only IPv6 addresses
will be tried (Mozilla should try both!)
now, in case of localhost:3128, since localhost is listed in /etc/hosts
list as being dual stack host (::1 and 127.0.0.1), it falls into the
3rd bullet. since Mozilla tries ::1 port 3128 only, it cannot
contact IPv4 squid waiting at 127.0.0.1 port 3128.
someone needs to convince Mozilla guys to use getaddrinfo properly.
