    Nice to see continued investment!

    We fixed a very old bug in our HTTP/2 Upload codepath which restricted performance on faster networks.

    This was pretty huge, a lot of people have run into this over the years.

    Andrew Creskey exposed internal necko timings to PerfStats so that they can be measured within our performance test infrastructure. These are also visible from telemetry on this dashboard

    Very cool. I can just imagine how this may work when you instrument it so that Firefox can never get slower at networking.

    WebTransport released in Fx114 on 2023-06-06

    I may have seen something about this, but as with a lot of the underlying code, it can be easy to miss what it means -- seems pretty cool and should enable some interesting new functions, especially on mobile.

    There's more stuff in there, but this is some of what jumped out at me.

  • I wonder if that HTTP/2 fix actually fixes uploads to places like YouTube.
