  • Next merge is Week of 2013-01-06
  • Fx18 Beta 1 shipped

Major Topics for This Week

Private Browsing

First set of patches have been reviewed. Likely to land this week. This will allow for initial PB testing in Nightly.

Fx17 & ARMv6

Quick napkin calculations show a slow uptake of ARMv6 devices over the first week of Fx17. As of Nov 26th, we have 0.1 % of active device installs on ARMv6. For comparison, we had ~1% when Fx17 was on Beta.

Stand ups

Suggested format:

  • What did you do last week?
  • What are working on this week?
  • Anything blocking you?

Please keep your update to under 2 minutes!
