Disable IPv6

From MEPIS Documentation Wiki

The way Firefox configures its use of the internet protocol IPv6 can slow down your connection. To disable IPv6 in Firefox:

1. In Firefox in address bar type: about:config
2. In Filter field enter: ipv6
3. change the value for network.dnd.disableIPv6 to true

---

Since other applications such as Opera or Thunderbird can also experience this slowdown, you may want to turn off IPv6 system-wide. To do this, open a console and as root enter:

  echo "alias net-pf-10 off" >> /etc/modprobe.conf

This change takes effect after a reboot.

Thanks to Stefan_Nicolau for this tip.
