Product Development

Firefox Project

Some recent work:

  • Tab Matches in Awesomebar landed. Woop!
  • EM API and UI work still in code review.
  • Looks like, for a quarter, we'll net about 44% of all i/o moved off main thread, with two bugs in review to bring us to > 75%. I'm looking at you, Novotny and Duell!
  • Glass turned on for Windows theme, but then turned off due to some nasty bugs (see, e.g., bug 450767 and follow up bugs)

Web Dev



  • Newsletter going out today

  • testing:
    • Working with metrics on continued tests on the download page for IE users...current focus is on optimizing for page load time, and this seems to have a huge impact on download conversion. Will implement any relevant findings in the short term, and will use this info (speed=good) as a building block when we redesign the site later this year.
    • Working with metrics and Sean Martell to tweak the first run page design, again based on some recent tests.


  • l10n changeset signoffs - who's doin' 'em, and who's allowed?
