  • Next on Necko triage: Kershaw

• Round Table

  • (greg) HTTPS upgrade tracking telemetry https://bugzilla.mozilla.org/show_bug.cgi?id=1883954 

    • Yeah, looking at the bug I see that consolidating seems to break continuity in the existing probes. I think it's fair to keep them separate for now. I think we'll still be able to draw meaningful conclusions from separate sources

    • Any concerns if we leave it as is?

  • (vg) WebSocketStream · Issue 970 · mozillastandards-positions 

    • Randell Jesup what do you think?

    • Randell to file for standards position, current assessment is negative as this functionality is best supported with WebTransport over H2

• Active Projects roadmap 

  • Active Projects: Fx124 rel Mar 19, Fx125 soft freeze Mar 14 

    • OMT: Move OnStartRequest and OnStopRequest to the content process (paused, target: TBD)

      • 1874464 - Turn on native HTTPS resolver on Nightly landed!

        • Currently disabled on OSX due to intermittent crashes in dns_res_send - see Bug 1882856 - Marionette crash in dns_res_send with network.dns.native_https_query on OSX

        • Platforms where it currently works: Windows 11, Linux, Android 10+

        • Platforms where it doesn’t work: OSX, Windows 10, Android 9 and lower

      • Should it ride the trains or stay in Nightly?

      • Will send intent to ship soon.
