    • Jan took care of a bunch of the work leading up to this, but that took longer than expected.
  • [DONE] clarify design and spec issues around Fetch for Service Workers to ensure they're implementable (annevk)
    • ServiceWorker work is not blocked on the Fetch spec at this point, and our implementation of Fetch is moving along.
  • [MISSED] implement gecko side of manifest spec (bug 997779) (marcosc)
    • Implement processing of V1 members (name, orientation, display, icons, start_url).

  • [MISSED] finish device orientation spec with Mounir (marcosc)
    • Write tests for all conformance requirements.
    • Publish LC by Monday, June 30.
    • work has been done here and is waiting on the review of others and integration afterward
    • a re-write has begun here and it didn't happen by the end of Q2


  • [MISSED] 941796 Generational GC on Firefox OS [Scale FirefoxOS]


  • [MISSED] Sandboxing support: create and update cached structure of the accessible tree in the parent process (tbsaunde)

    • About 40% completed.
  • [DONE] FFOS/GAIA: fix 9 P1 Gaia accessibility bugs (there are 9 total at time of writing)
