For a regular web page such as slashdot.org, Firefox needs to resolve more than 40 domain names. Each domain name is resolved twice, once for an IPv4 address and once for an IPv6 address. This results in lots of DNS requests, slowing down your web access. If you are like 99.999% of the population without IPv6 access, translating domain names in IPv6 addresses is useless.

To disable this functionality, type
about:config
into the (firefox) address bar.

type
ipv6
into the search bar

and toggle
network.dns.disableIPv6 to true


This still works good!
