As of Monday, Sept 19, we have hit 27.6M DAU on Firefox 48.0.2. Now that we are in a new Release Cycle, we expect the data to catch up by this time next week for 49.0 and 49.0.1
Biggest news is that we enabled E10s with users for our Whitelisted Add-Ons and for Add-Ons created as WebExtensions as of Firefox 49. We are in a similar situation as we were for 48 in that the Release population is skewed in that automatic updates for disabled for Windows users due to a websense crash. We have shipped 49.0.1 today to fix this so we should have a better grasp on how things are going next week.
Top Issues
Investigation continues for bug 1300411 - user reports excessive load spinning when switching tabs with e10s in 48.0.2 release. Here is what we know:
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.
We are also disabling e10s for users who are experiencing the spinner upon opening a new tab. This will be included as a ridealong for the next dot release for 49 (if we decide to ship one).
Another top issue has surfaced this week; we have disabled E10s for the Russian Locale since the crash impacts a popular email site. Once the fix lands, we plan on re-enabling E10s. We would need to ship the fix in a dot release for 49 and is being considered a ridealong at this time.
[ON TRACK] Add-Ons + WebExtensions
We shipped 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.

bug 1277831 E10s support for RTL versions of Firefox on Windows and Mac is on trackfor Firefox 50. Softvision has just signed off on RTL support for e10s in their mid-aurora sign-offs.
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.
