footnote Starting in Firefox 70, a value of disable_non_proxied_udp requires a proxy if one is configured, but allows connections to go through if no proxy is set up. Previously, in this mode WebRTC could only be used if a proxy was configured and TURN over TCP was available; this behavior is now exposed as proxy_only.
