Facebook, https and ipv6

I wasn't able to set up secure browsing on Facebook using the old internet but, when logged in using ipv6 https://www.v6.facebook.com/Alan.Clifford, I was allowed to. On the legacy, ipv4 internet again, I was still set up to use https.

Chat seems to be no longer available on the Facebook site under the old internet but that doesn't matter; I use ipv6 at home and have Facebook chat set up in Adium anyway.
