On the contrary, Firewalls are configured today to permit UDP port 53 and block TCP port 53. Why should firewalls change their configuration ? DNSoD does not require any changes to the Firewall configuration. Browsers already support DTLS because of WebRTC (SRTP-DTLS for media streams, SCTP over DTLS over UDP for data channels).
