Roadmap Discussion

Roadmap

Notices / Schedule

• We are here on the schedule. This is the time for speculative low-risk fixes on Beta and other less critical fixes prior to convergence in Beta 5 and Beta 6 (where we restrict what we land).
  • We shipped Firefox 10.0.1 unthrottled last Friday (2/10). We're tracking a few issues post-release
  • Our third beta for FF11 will go-to-build today, ship on Friday (2/17)

• Please take a look at bugs currently tracked for FF11's release
  • If the bug no longer needs to be tracked, please fix the flags and comment to that end
  • Please make sure to progress other investigations and email Alex if you're blocked

• We've finalized the ESR Landing Process and filed bug 726893 for the flag changes

• Lukas Blakk (of RelEng fame) will be helping with Release Management triaging, tools work, and the ESR branch in the near future!

Performance

• Snappy weekly summary on Taras' blog
• Lots of frontend Telemetry probes are landing. See bug 671038.
  • Some of this has already paid off in terms of us catching a tab animation regression in bug 724349.
• Plan to switch our awesomebar searching from SQL to an FTS. If you are a text-search/tokenizer expert, perhaps you help us with bug 725821.
• Killing Firefox start-up inefficiencies on Windows. Check out the details on Brian Bondy's blog. Brian’s blog post contains tips on xperf, Firefox profiler, about:startup – read it.
• Olli has landed most of the cycle collector fixes. Telemetry shows a dramatic reduction in cycle collection times for Firefox 13. He and Andrew are investigating the remaining causes of long CC times.

Layout

• Lots of preparation (testing/analysis) for unprefixing/emulating specific webkit CSS properties
• Fixing remaining Font Inflation P1 bugs.
• CSS flexbox support for absolute/relative -positioning children
• Graphite font support testing has started
• Harf-Buzz text engine update landed (bug 695857)

Network

• SPDY testing (on by default) on trunk is going well. We are not planning to turn it off (may ship with it on in Firefox 13) unless something serious comes up.
• We've started on our DASH (adaptive streaming) implementation for the video tag. Steve Workman and Jason Duell are leading this effort.

Plugins

• Patch for bug 501485 landed on inbound today: Destroy plugin processes after three minutes of not being used. Timer starts when the last instance is destroyed, is canceled if a new instance is created before it fires. Keep an eye out for any issues.
