With the intent to unship TLS 1.0 and 1.1 https://groups.google.com/forum/#!topic/mozilla.dev.platform/8EFRYDR3N1c <https://groups.google.com/forum/#!topic/mozilla.dev.platform/8EFRYDR3N1c> we don’t want to leave Firefox users left with the old DTLS 1.0 when using WebRTC.
The latest draft on WebRTC security architecture (which soon going to be published as an RFC) requires all implementations to support DTLS 1.2 https://tools.ietf.org/html/draft-ietf-rtcweb-security-arch-20#section-6.5 <https://tools.ietf.org/html/draft-ietf-rtcweb-security-arch-20#section-6.5> In Firefox 71 we landed user prefs which enables developers to test their WebRTC services with DTLS 1.2 only. Chrome has announced to also turn off DTLS 1.0 for WebRTC in M81 https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!topicsearchin/discuss-webrtc/dtls;context-place=searchin/discuss-webrtc/PSA$3A/discuss-webrtc/Dsq_14_WoUk <https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!topicsearchin/discuss-webrtc/dtls;context-place=searchin/discuss-webrtc/PSA$3A/discuss-webrtc/Dsq_14_WoUk> Last time when we measured DTLS 1.0 usage was 1.88% in Firefox 68 Beta https://telemetry.mozilla.org/new-pipeline/dist.html#!cumulative=0&end_date=2019-06-18&include_spill=0&keys=__none__!__none__!__none__&max_channel_version=beta%252F67&measure=WEBRTC_DTLS_PROTOCOL_VERSION&min_channel_version=null&processType=*&product=Firefox&sanitize=0&sort_by_value=0&sort_keys=submissions&start_date=2019-03-10&table=0&trim=0&use_submission_date=0 <https://telemetry.mozilla.org/new-pipeline/dist.html#!cumulative=0&end_date=2019-06-18&include_spill=0&keys=__none__!__none__!__none__&max_channel_version=beta%2F67&measure=WEBRTC_DTLS_PROTOCOL_VERSION&min_channel_version=null&processType=*&product=Firefox&sanitize=0&sort_by_value=0&sort_keys=submissions&start_date=2019-03-10&table=0&trim=0&use_submission_date=0> We want to disable DTLS 1.0 in WebRTC together with TLS 1.0 and 1.1 in March 2020.
