Schedule Update

  • Desktop 39 beta 4 shipped on Wednesday
    • a day late because of the build infrastructure outages
  • Still waiting for mobile beta 4 signoff, should be soon.
  • I think we should ship mobile beta 5, to turn off async stacks.
  • 39 Beta 6 will go to build next Monday.


  • No updates.


  • Kairo is on PTO next week so we will likely have smaller stability updates
  • Marc Schiffer is covering for update testing and dmajor for stability

Aurora / Dev edition

Overall rate: 3.1 (target: <1.5)

  • Pretty unchanged to Tuesday.


Overall rate: 1.9; plugin crashes/hangs: 0.11/0.40 (target: <1.4, 0.8/0.12)

  • In early 39.0b4 data, we see our famous AMD crash (bug 772330) again, 3.8% of all crashes, this time as js::LifoAlloc::getOrCreateChunk (and dmajor's patch doesn't help in that location).
  • bug 1159751 (new gfx shutdown hang) is 2.6%
  • bug 1170141 (real player, startup) is still visible in stats, despite blocklist (still outstanding: 1172560)
  • bug 1170143 (Intel gfx, a lot on startup) is not gone but down to 0.9%
  • bug 1146313 seems to be fixed by the gfx patches that landed!
  • async plugin init is probably not ready to be shipped, see still high hang rate


Overall rate: 1.25

  • No news.

  • status report on NSS 3.19.1
   Logjam. Response, update NSS. this broke some other things (also for chrome and redhat)
   the NSS team is working to fix that.
  • RC4. It should remain in the state it was in in 38. But is it? Not sure. Working with rbarnes to ensure that.
  • turning off async plugin init. Will be turned off in beta 5 or 6. Status report (aklotz)
  • url sharing in hello is still on track for release.
  • async stacks turned off in beta/release. Coming in beta 5.
  • supporting hotfixes with new addon signing requirements. Still needs verification. bug 1151537
