Media

  • [ON TRACK] WebRTC enabled by default (not behind a pref or config flag) in time for Firefox 20 uplift
  • [ON TRACK] Land media platform decoding functionality for Android's Gingerbread and Honeycomb OSs in mozilla-central. One target device for each OS will be identified and agreed upon by Media and Android to verify functionality. Success criteria: platform decoders running in Firefox will playback videos at a similar performance metric to the videos playing back in the default browser on the same device.

  • [MISSED] new binding for HTMLDocument
    • The work that we planned to do here is done, but an unforeseen issue that came up when implementing, relating to the need for a new proxy for dealing with the goofy behavior of element ids shadowing properties on the prototype, caused us to miss the overall goal.
  • [ON TRACK] new bindings for 10 HTML element classes
  • [DONE] make calling new binding callbacks easy and safe

WebAPI

  • [CARRY OVER] Temporary storage for IndexedDB (bug 785884)

  • [ON TRACK] Assist with reducing memory usage and increasing performance of B2G (bug 797189)
  • [ON TRACK] Make B2G v1 a high quality release

Perf

  • [CARRY OVER] 662444: call exit(0) on shutdown
  • [CARRY OVER] 661881: Bundle about-telemetry extension to ship with Firefox
  • [CARRY OVER] 769241: Make libunwind work on ARM
  • [CARRY OVER] Prevent, to a reasonable extent, background tabs from starving the main thread

Networking

This was a productive quarter but we ended up doing a lot of things that aren't on goals here (e.g. rewriting DOM storage [600307], improving Stone Ridge, network resource load prioritization [792438]), and we made great progress on goals we ultimately missed (e.g. DASH). B2G work was much more than we expected, taking up 2.5+ team members for the entire quarter.

  • [MISSED] Resolve all networking basecamp blockers that are marked as blocking before November 1st.
    • This work will be done primarily by Jason Duell, Honza Bambas, and Brian Smith.
    • This just turned out to be way more work than we thought, including new blockers that we took on. This matches the organization-wide trend.
  • [AT RISK] 713933 Enable TLS false start for NPN/SPDY in mozilla-central.
    • Patrick McManus will lead this effort.
    • Code is done, just waiting on reviews which are held up by B2G blocker work.
  • [MISSED] Remove all potentially blocking disk cache API usage in nsHTTPChannel and nsWYCIWYGChannel, on mozilla-central.
    • Nick Hurley and Michal Novotny will lead this effort.
    • Didn't get it done. Nick Hurley moved to other projects.
  • [MISSED] 702122: Have full adaptive DASH for WebM video enabled by default on Aurora.
    • Steve Workman will lead this effort.
    • Didn't make Aurora, but did make mozilla-central.
  • [MISSED] Resolve all networking security bugs that received a designation of sg:moderate or higher more than six weeks ago. This is a permanent goal for the group.
    • No sec-high or sec-criticals unresolved. We're only missing this goal because we have high standards including sec-moderate!
    • One old sec-moderate bug, bug 660749, remains unresolved. Brian Smith was working on the B2G security model instead.

Plugins

Mobile

  • [ON TRACK] Resolve all mobile security bugs that received a designation of sg:moderate or higher more than six weeks ago. This is a permanent goal for the group.

  • [ON TRACK] Implement support for H.264 on GB on trunk [bug 787228]
