Pages as Facebook and Youtube in Firefox became much faster after I have set true network.dns.disableIPv6 in about:config. Why?

Speed became very similar as in case of Google Chrome was originally without any fine tune.

Thanks & br, Halacs

  • You may have broken IPv6 in your ISP or your home router. Try a firmware update of the home router. – Michael Hampton Jul 6 '18 at 21:54
  • I have a Mikrotik router with the most recent firmware.ipv6-test.com is reachable without any warning. Do you have any concrete idea what should I check there? – Halacs Jul 8 '18 at 14:26
  • Maybe your DNS servers? It's hard to know for sure. – Michael Hampton Jul 8 '18 at 14:43
