DNS-over-HTTPS Policy Requirements for Resolvers
Our plan is to select a set of Trusted Recursive Resolvers (TRRs) that we will use for DoH resolution in Firefox. To that end, today we are releasing a list of DOH requirements, available on the Mozilla wiki, that we will use to vet potential resolvers for Firefox. Not just for our potential DoH partners, but for all DNS resolvers.
