Firefox slow in Ubuntu. DNS lookup fix.

Problem: Firefox takes an age to resolve host addresses in Ubuntu.

Solution:
Open Firefox,
type about:config into the address bar, press return,
Scroll down to the entry network.dns.disableIPv6 and set it to TRUE (with a right mouse click).
Surf away.

This is a bad solution. The right piece of advice is: „Go get IPv6, man!“ You automatically have 2^80 IPv6 addresses with every single public IPv4 address. So why don't you people just use them? You do not need any assistance from your ISP. Just find out how 6to4 works and go ahead. Sticking with IPv4 from 1975 is ... somewhat shortsighted, to say the least. Needless to say that there are no allocatable IPv4 addresses left.
