Firefox OS

Firefox Mobile

Open Sans and Charis for Content
  • As part of the Readability 2.0 feature, bug 831354 – Ship fonts for content in Firefox for Android landed in central after a heroic effort on part of UX and Johnathan Kew to correct test failures and provide follow up patches such as bug 831883 – eliminate the Open Sans fonts bundled in the Reader core theme, just use Gecko’s “installed” copy in order to are mitigate the resulting package size increase by about ~200k. this also happens to fix bug 792370 – Reader Mode lacks proper italic and bold faces for Open Sans.
  • We are also looking into a possible talos regression bug 833000 – Talos Regression trobopan on Android, 40%, Jan 19
  • Once we have the above issue nailed down, we will figure out if this will ride the trains for Fx21 or if we’ll uplift to Fx20
Memory, Responsiveness, Usability
  • Regression in fX21 fixed: bug 831188 – about:plugins lists blocklisted and user-disabled plugins
  • Also part of the Readability 2.0 effort, a prototype is under test/iteration bug 757257 – font inflation element grouping
  • Fix for IME regression has landed and is being targeted for aurora bug 825120 – Previous composition is not cleared when changing focus from old to new input
Stability Wins
  • bug 830131 – java.lang.NullPointerException: at org.mozilla.gecko.InputMethods.needsSoftResetWorkaround( which we are also targeting for aurora
  • bug 827176 – java.lang.NullPointerException: at org.mozilla.gecko.GeckoInputConnection.notifyTextChange( at org.mozilla.gecko.GeckoInputConnection.endBatchEdit( which we are targeting for aurora and beta
In progress/under investigation
  • bug 826385 – “Clear private data” not clearing cache.

Stability Report [Weekly]

  • Trunk bugs needing traction:
    • bug 827946 (Linux, skia::BGRAConvolve2D), no comment from Joe in a week and this is huge for a Linux crash (>3% of all crashes).
    • bug 830654 (js::ObjectImpl::getPrivate), needs owner
    • bug 827171 (nsPluginStreamListenerPeer::OnStartRequest, mobile), needs owner, also affects Aurora seriously

Snappy [Bi-Weekly]

  • Jan 17 status
  • Snappy updates move to bi-weekly after next week

Memshrink [4th Tuesday of Month]

  • The new, easy-to-use version of DMD landed. about:memory is our main tool for understanding and reducing memory consumption, and DMD is our main tool for making about:memory better. It was particularly helpful in improving our understanding of B2G memory consumption.
  • A bad memory consumption regression has made it onto Aurora. It relates to a refactoring of image-handling code. Seth Fowler is investigating. We wouldn’t have noticed this without AWSY.
