This page is to track testing of Firefox 59 from mozilla-central (Nightly) through to mozilla-release. This is intended to be a minimal set of information to help Firefox QA understand and communicate the quality of upcoming releases. Our current walkthrough of the release and QA process might be changing due to recent reorgs.

The QA efforts are mostly split up between two teams:

  • Engineering QA
    • team reports to Ryan VanderMeulen and Tom Grabowski
    • the Project Manager (and main contact) for the team is Rares Bologa
    • team is based in Romania (most part) and Las Vegas (5 people)
    • the team mainly tests the Desktop app, but covers the Mobile (Android, iOS) side as well
    • main responsibilities:
      • Feature Testing - new Firefox features, prior to landing and during Nightly
      • Bug Triage - older as well as incoming Unconfirmed bugs
      • Bug Investigation - various investigation as requested by other people (e.g. finding steps, setting component, finding regression windows)
      • Misc - other miscellaneous requests
  • Release QA Desktop and Release QA Mobile
    • team reports to Ryan VanderMeulen and Tom Grabowski
    • the Project Manager (and main contact) for the team is Andrei Vaida
    • team is based in Romania
    • main responsibilities:
      • Build Validation - mostly Beta, Release, and ESR builds (including automated ondemand update, and throttling tests)
      • Feature Testing - new features not covered by the Engineering QA team, and those covered by the Engineering QA team after they enter Beta
      • Bug Verification - verifying the most important / high risk fixes, with focus on those closer to release
      • Bug Investigation - various investigation as requested by other people (e.g. finding steps, setting component, finding regression windows)
      • Misc - other miscellaneous requests
