Perf P2 bug 1174770 - tpaint regressions (3%-8%) in e10s mode compared to non-e10s mode
- bug 1262946 - Don't focus the initial browser in a new window until it has been painted
  - This had a really great impact on tpaint across the board - ignore the Windows XP stuff, since that's kinda been tainted by the disabling of e10s stuff that happened recently.
- Really close to the 5% threshold now. cpeterson has given his opinion that we should move on.
  - Hoping to drive towards sign-off of all UI responsiveness borderline regressions, leaving only tps
Perf P1 bug 1186585 - 19.66% - 44.84% tps talos regression with e10s enabled and APZ disabled
- I'm reasonably certain the test is flawed in its measurement, and is favouring non-e10s. See my arguments in bug 1261152
- Currently in the process of re-writing part of tps to be more accurate. Initial results look promising, hoping to have solid data from a try push tomorrow.
bug 1263887 - [e10s] The dropdown selector is not working properly.
- We triaged this last Tuesday, and I was asked to do investigation. The problem is that script on the page is mutating the <select> dropdown after it has opened.
Fixed regression bug 1260461 - Firefox fails to exit on system shutdown
- This has now been uplifted to aurora / beta. Waiting to hear back about ESR.
Fixed regression bug 1255773 - Page Info - Media is incomplete

Worked on fallout from bug 1235633 (perf problems and jemalloc4 regression).
Continuing to work on OOM issues. May move to bug 1262671. Will talk to mccr8 first.

A lot of reviews and feedback

bug 1247420 - (m9 1255138 - Resizing windows from JS is not supported in e10s mode) - Mostly completed, it needs some tuning/testing. There is an offset issue with sizeToContent which I might file a followup for...

bug 1264383 - (Add-on multiprocess compatible shims stops TabSelect event listeners being removed from the tab container) - shims bug, filed a bug for it, probably should be uplifted...
bug 1099406 - (regression in SIMPLE_MEASURES_FIRSTLOADURI) - probe was completly broken, I would not bother fixing it unless there is a good reason for it.

lots of reviews, mostly addons

Having conversations with :cpeterson, :erahm, :rvitillo about MEMORY_TOTAL and how ipynb analyses can look different from t.m.o dashboards.
