Scott (jwir3)

Last Week:

  • Developed a demo video for reflow-on-zoom. It's available at: refloz.ogv (Also, there's an apk build at the same location: refloz.apk - It also has the maxRatio preference available, too. If you choose to try it out, keep in mind it's still pretty rough.)
  • Worked on bug 784375: Add ability to specify a maximum font inflation ratio. It's in review, but I'm trying to get it to reflow when prefs change.
  • Isolated behavior for -webkit-text-size-adjust: percentage%. It appears to simply increase the specified font size. Still performing a few more tests before adding it to the spec-in-progress for this feature.

This Week:

  • Still working to fix quirks in reflow-on-zoom prototype.
  • Assisting mbrubeck in debugging issues with bug 716575 where patch 3 of the series is crashing talos (on apparently an NS_SUCCEEDED(xxx) operation?!?!) We're not entirely sure how to reproduce- it seems to only happen in Talos tests (mochitests and reftests pass just fine...) I'm going to try and see if I can get talos running on my phone to see if I can shed some light on this problem. We don't have any information from logs, because when it crashes on talos, we don't even get a browser_output.txt file. :|
  • bug 790645: Font inflation enlarges text when reloading content in form inputs after zooming


Last week

  • in Warsaw for performance work week
  • bug 727352 - get rid of JSON usage in viewport updates
  • bug 785291 - add support for in-product fonts, reading from extracted res/fonts
  • bug 790614 - report broken mobile site feature, a little controversial

This week


  • unable to reproduce CM crashes



  • Minor patch to clean up aboutHome.xhtml a little
  • Filed bug to set aboutHome favicon in Java and remove it from aboutHome.xhtml (bug 792240)
  • Filed bug to use ABI in multiple-APK filtering (bug 791267)
  • Digging into how to support Google Campaign Tracking
  • Some Metro planning work


  • More reviews
  • More product planning work
  • Maybe a patch or two?
