   In case you're wondering why some things IPv6 don't work, here's a useful service: http://test-ipv6.com/ . Guess what: I found out that my Firefox was set to (default!) disable IPv6 DNS lookups - only direct-to-IP connections would work. I had no idea (and why on earth would that be the default - still)?? #networking #ipv6 #firefox

     After correcting that, and testing again, I get: "Your browser has real working IPv6 address - but is avoiding using it. We're concerned about this." Seems to be related to another setting, for "fast fallback" (Chrome/Chromium has this mechanism, too): test both connections, if IPv4 is faster, comntinue with that... #networking IPv6 #firefox #chrome #chromium #fastfallback

     In Firefox this setting is called network.http.fast-fallback-to-IPv4 (was set to default boolean true). I set it to FALSE but that doesn't seem to change the test result :( #networking #IPv6 #firefox #fastfallback
