Details

webextensions.settings.services.mozilla.com has AAAA records, but refuses connections on its IPv6 addresses. This means IPv6-only networks and dual-stack networks that prefer IPv6 all fail to connect.

Either IPv6 access should be fixed, or the AAAA records removed so IPv4 fallback works.

It looks like we are using a VPC ELB, which does not support IPv6. I've removed our AAAA records.
