Kilimanjaro
- Product team working on solidifying requirements for “base camp”.
- Still working toward larger Kilimanjaro goal.
- Triage today at 11:30am. Conflicts with the daily mobile triage. Trying to find another time that would enable mobile folks to attend.
Notices / Schedule
- Fennec Native 14 beta 1 is now live on Google Play!
- Bugs filed by following the link on the product page will have [Play] in the whiteboard
- With Fennec Native on Google Play, we’ll be including betaN+ blocking bugs during channel meetings, but we’ll continue triaging nominations and release blockers as part of mobile triage
- Fennec Native betas will have a weekly cadence after this week as with desktop, going to build no later than Wednesday for a Friday push
- We expect our next beta of Fennec Native to be multi-locale with the same 13 localizations as XUL Fennec previously
- We’re now here in the schedule
- FF13 beta 4 will go-to-build today (5/15). Please land any approved beta patches ASAP, and continue working on tracked bugs
- We should be looking for the lowest risk mitigating fix for remaining tracked bugs
Firefox Development
- The work by a group of MSU students to get Firefox preferences “in-content” has mostly landed on trunk. Check out Jared’s blog post for more info. There’s some followup polish/theming work still remaining before we make the switch and remove the old preferences dialog.
- FX-Team work week wrap up – read it, there’s good stuff in there!
Firefox Developer Tools
- Developer Toolbar relanded. Preffed off, turn on devtools.toolbar.enabled to try it out.
- Async web console starting to land, 2 of 5 patches landed.
- Responsive Design Mode should be landing this week.
Add-on SDK
Performance
- Perf+metrics work week this week in MV/SF
- This week’s Snappy summary
- Lawrence posted on hacks about Firefox 13 Snappy work.
- Tim landed a fix to avoid setTimeout()s when handling tab clicks in bug 743877, which should significantly improve tab strip responsiveness.
- Incremental GC making progress towards being turned on by default again (bug 750959, bug 752098).
- Wladimir Palant (Adblock Plus fame) wrote a new Suspend background tabs add-on to halt activity in background tabs. This experimental add-on should give a sense of how we can improve lag due to background tabs.
GFX
- Azure-Thebes will (hopefully) be turned on by default this week.
- This applies only to hardware accelerated computers on Windows Vista and 7.
- The net of this is that we’re going to be drawing fundamentally differently, and we can expect regressions in performance and drawing.
- It has a very simple pref for backing out, luckily.
JS
Layout
Video
DOM
WebAPI
- Lots of work happening on security model, but still a lot of work remaining.
- We will probably adjust the open-web-apps API to allow multiple apps per origin since the security model will support that. Might not implement the actual support in the initial release though.
- The Open Web Apps API has been submitted to W3C and we’ve started receiving input.
- Initial APIs for “system intents”, camera control and Alarm API being discussed on webapi mailing list.
- Started implementing backend for doing apps-specific permissions.
Network
Identity
Firefox front-end team met with Ben Adida & Co. last week for an Identity swarm, made good progress on understanding how things work, and getting some initial code up and going to start flushing out issues (for both sign-into-browser and native sign-into-websites)
Plugins
Mobile
- In light of the beta, please remember that one can have only one native Sync client per device. Please ping :ally if you have questions.
- Testday on Friday please help promote it
Accessibility
- No audible this week.
Tree Management
- Switching windows 32-bit PGO builds to run on 64-bit machines this week bug 753132
- Hoping to have signed OSX builds (for 10.8) on mozilla-central late this week or early next week bug 752613
Security
- module owners please check your module for unassigned security bugs

- bug 572011 – Crash @ nsDiskCacheStreamIO::FlushBufferToFile
- bug 597260 – nsFileOutputStream::Write(char const*, unsigned int, unsigned int*)
