Notices / Schedule

• FF 17.0b2 go to build today
• FF 17.0b2 mobile ships Friday Oct 19th
• FF 17.0b2 desktop shipping Monday Oct 22nd at 7am PT
• Just a reminder: 16 users are currently seeing warnings that Mac 10.5 will be de-supported starting with 17

Firefox OS

• Blocker dashboard v2: http://people.mozilla.com/~dietrich/basecamp/blockers.html. Not complete yet, doesn't have whole set of blocker owners.
• Daily triage is fun. Schedule and connection information. https://etherpad.mozilla.org/b2g-triage-plan
• Lots of regressions on both Gaia and platform STILL. Stephend's team landing some integration test automation soon. Lack of Gaia unit test automation, and JS integration test support are big barriers to getting testing to be second nature for that team.
• Dogfooding devices are in, porting mostly complete. If you're working on B2G bugs and need a device, file a ServiceNow request for an Unagi device and clearly state that you need it for development, not regular dogfooding.

Firefox Development

• Ehsan and Josh Matthews have been on a rampage fixing per-window private browsing bugs. Much of the back-end work is complete, remaining issues are mostly front-end.
• Work on the download panel is picking up, thanks to Mike Conley with help from Paolo, Marco and Mano
• Robert Strong has been putting in a herculean effort to get the stub installer ready to ship
• Social API bugs continue to get squashed as we approach beta testing, thanks to Mark, Shane, Felipe and Jared

Firefox Developer Tools

Add-on SDK

• Working on automatic re-packs

Performance

• This week's Snappy summary

• Jeff's fix to half tab switch time on image heavy sites had an unintended consequence of image flicker when tab switching, which he has now fixed (bug 799335)
• Jeff updated Telemetry to capture the total tab switch time - see the Telemetry dashboard for live data and the histogram below for a sample

• BenWa updated the Gecko profiler to capture most of browser start-up (bug 799638)
• In a good demonstration of the value of Telemetry, Vlad used chromehang data to confirm that Patrick's fix to remove proxy main thread IO (bug 769764) has eliminated all proxy related jank

• Some hang signatures currently end in a kernelbase.dll frame, probably Windows symbols not picked up after patch Tuesday - but hangs aren't really actionable atm anyhow
