Release Engineering

  • WinCE:

    • Which branches need regular wince builds / l10n? Currently doing them on mozilla-central, mozilla-1.9.2 and lorentz. How about releases?

  • Due to a bug with add-on submissions, some add-ons aren't in the review queue that should be. How to tell if you're affected
  • blog post on Contributions sources
  • YSlow 2.0.5 (3.6 compatible) caused crashes on Windows and Mac. 2.0.6 fixes Windows crash, but Mac crashes caused by separate issue.

Web Dev




  • 3.6 release stuff:
    • launch on went really smoothly thanks to the work of IT, WebDev & QA
    • seeing good increase in Personas usage, Twitter followers & Facebook fans thanks to improved First Run page (more stats to follow)
    • next steps: working on 2010 roadmap for ways we can continue to optimize our sites. Will share details soon.
  • Plugin Check page
    • Was getting an average of 40K views per day.
    • After launch, seeing an average of 90K pv/ day


  • Pike would love feedback on his "purpose of nightlies" thread.
  • OOPP just got turned on by default in mozilla-central (bsmedberg to blog shortly). We will need lots of testing, so please use mozilla-central nightlies of Firefox, see for download links! (Windows/Linux, Mac doesn't have OOPP for this cycle).
  • when will we advertise updates from FF3.5.7 -> FF3.6 to users?
    • need to first evaluate data from release
    • usually takes a week after release to gather data, then a few days to analyse
    • hope to have decision made early next week, would like to be aggressive
  • decision about offering major updates from FF3.0.17 -> FF3.6
    • premature to discuss this until QA has completed their checks
    • if it checks out OK, should make the update available (but not advertised)
    • decision to advertise will be made as per above
  • discussion about End-of-life for FF3.0.x
    • our policy is that there's a minimum of 6 months support after n+1 version is out; it's only just been 6 months
    • still working to migrate users to newer versions, no plans to end support yet
    • before we do end support, we'll communicate broadly to the development community and to our users
