content: This looks like an attempt to smuggle in browser DNS under the banner of privacy, the result of which is a browser take-over of DNS operation away from the OS.  Bingo! This is step #1 for browsers to do two things: 1) Monetize users' DNS queries by controlling the default resolvers, 2) Extend Silicon Valley control over online speech by using DNS to block access to "wrong think." Anyone want to start a wager pool on when it will become impossible to override the browser's internal DNS resolvers?
