bug 1298219 - about:sessionrestore shows a crashed tab after force-quitting the machine twice
- Fix with a regression test landed on central, and should be in today's nightly. Will request uplift to Aurora soon.
bug 1300411 - user reports excessive load spinning when switching tabs with e10s in 48.0.2 release
- Several reports of this have caused some concern
- We've landed a probe in bug 1301104 to figure out how bad the bad spinner cases (>1s) are, and hopefully how frequent
- bug 1301131 has been filed with a tentative plan for disabling e10s if a user sees long spinners too often
bug 1287178 - "you have an unsubmitted crash report" even though crash reporter is disabled
- Adding a "submit always" button. Currently refactoring and adding automated tests.
- This hooks into bug 1241459 - [e10s] A crashed background tab does not give option to submit, which will use the same notification mechanism
bug 1255843 - Develop a tool to measure resource usage of each subprocess
- Rutuja has finished this work, and the tool is available in about:performance
- Some follow-up bugs have been filed, which she is interested in hacking on! \o/

Nothing specific to report on the e10s front; I'm sill waiting for all the required machinery to land in order to get client-side stack traces for content process crashes but that's taking longer than expected

Fx49 Beta (which was by far the safest add-ons and webextensions) was flawless
- rolling into Release - 3% or roughly 5 Million, with capability to remove in process
determining impact of file-system sandboxing on add-ons
- MPC:true or add-ons from last experiment not tested against sandboxing at all
  - hoping for experiment in that area. are there telemetry probes way to separate
  - would hope for against all population - or even 50 add-ons experiment population
50 move to MPC:true and MPC:webextensions experiment(~1600 named and more unnamed)

bug 1297549 - Main Windows a11y blocker - up for review
bug 1301217 - a11y+e10s stability fix
bug 1301167 and bug 1301184 - Make profiler and hang monitor aware of Windows a11y stuff
Once these land my focus is going to be on perf optimization and re-enabling tests.
