Firefox is loading painfully slowly…

aka Firefox, DNS lookups and IPv6 (under Arch)

Since my laptop is running with Arch, sometimes my Firefox makes me crazy when i’m trying to open a new page because it show a message like Looking up… for minutes !

After googling a few seconds i’ve found someting that is working for me…

  1. Go to about:config
  2. Search for network.dns.disableIPv6
  3. Set it to true

That is only a workaround because i have no time to debug the root cause.
