    • FF3.0.15 in ~16 hours
    • FF3.5.4 in ~12 hours


  • Add-on compatibility with 3.6 at about 50%, hope to get that up to 90% by release
  • Extend Firefox just ended, 64 entries to judge

Web Dev


  • Starting to see some use of Build your own browser. Moving forward, will be looking at adding customizations, and are actively looking for feedback via BYOB's contact page.
  • Would like to consider re-introduction of unbranded builds based on release code for use by groups who currently modify installers to remove brands prior to distribution (there's a lot). Requires broader discussion on impacts, but wanted to give folks a heads-up that requests to RelEng and others will be coming.


  • Docs are underway.
  • Plans are here, coming together:
  • Initial changes for under the hood done with Alix
  • Have a rough list of things to highlight vs. things that aren't that important
  • Plugin page launch planning underway with teams
  • WOFF launch planning underway
  • File API discussion underway
