e10s Update: September 2

Executive Summary

With the hotfix/48.0.2 release out the door and given that E10s enabled for Firefox 48 continues to be green, we have decided to increase activation for 100% of our eligible population bug 1299247. We have hit 1.86M DAU on August 30 and stability dashboard our crash rate remains within range of our release criteria. So far, our engagement ratio actually looks better for the E10s group but given that our release population has been fairly skewed, we need more time to draw a definite conclusion. It's worth noting that the we're trending in the right direction. If you have any questions about this data please just ping me or in #e10s.
How are things looking for Add-Ons in Firefox 49 Beta? So far, really good. There isn't any data that indicates we can't enable E10s with users for our Whitelisted Add-Ons and for Add-Ons created as WebExtensions.

A11y and touchscreen support has landed in 51! \o/
We're also looking into Windows touchscreen/a11y compat, see more information as the plan is taking shape, here.

We are at about 90% [https://wiki.mozilla.org/Electrolysis/Test_Coverage Test coverage for all channels. We have touched base with all module owners. Not all of them have signed off specifically but we are calling it within acceptable range for shipping at this point.

Bi-weekly meetings have commenced for e10s-multi, see more info:
