==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 [https://sql.telemetry.mozilla.org/dashboard/client-count-firefox-e10s-release- 1.86M DAU on August 30] and [https://sql.telemetry.mozilla.org/queries/613/source stability dashboard our crash rate remains within range of our release criteria]. So far, our [https://sql.telemetry.mozilla.org/queries/618#1037 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.

E10s Update: September 2

Executive Summary

  • As of Tuesday, Sept 6, we have hit 20M DAU and stability dashboard our crash rate remains within range of our release criteria.
  • Increasing the population impacts our Engagement Ratio data; we need to give the MAU data time to catch up since we've deployed the increase. More on this next week.
  • The top issue we are investigating is bug 1300411 - user reports excessive load spinning when switching tabs with e10s in 48.0.2 release. Here is what we know:
    • There are 3 individual reports. One of which that is the most reproducible seems related to an issue with 1279086 bug 1279086 google docs. Testing is needed to confirm.
    • In order to better surmise the scale of the this issue, we are landing opt-out telemetry probes as of Firefox 49 bug 1301104 and bug 1301435.
  • How are things looking for Add-Ons in Firefox 49 Beta? STILL GREEN. 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.

Next Steps

  • 09/12: Bug tracking and Team RASCI transition
  • 09/19-20: Retrospective to be scheduled

Add-Ons + WebExtensions

  • Everything is looking good for add-ons + e10s in the 49 experiments and as stated above, we will ship Firefox 49 with a set of compatible Add-Ons enabled.
  • Decision Made: We will continue A/B experiments on Beta and will maintain the same % of the population (50% of eligible).
  • General roll-out plan for including extensions is here.

A11y + Windows 8 Touchscreen Support

  • 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.

  • Details can be found, here: bug 1296279

Automated tests

  • 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.

Multi Process

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