e10s Update: August 5

Executive Summary

• We have shipped to 1% of of our eligible (41% of total) population \o/ and plan to increase the percentage to 10% as of August 15.
• The data we have in terms of crash stats is looking healthy and there are not any major issues that have surfaced since we shipped; have have a couple of [https://mzl.la/2aXCH8U possible ride alongs for 48.0.1 (a dot release which is being planned to handle a unrelated crash).
• The telemetry data we are able to collect indicates we are on track for our intended number of users; we won't have exact numbers for about a week. We had numbers initially because the number of users was low; now that the numbers are higher, there is a delay in obtaining the data.
• We had three blog posts:
  • Future of Firefox
  • Mozilla GA Blog
  • Add-Ons Blog
