• bug 1198459 (M8, Disable e10s if the user uses accessibility) - fixed. there are follow ups that didn't make the merge, flagged for uplift.
• bug 1227312 (M8, Crash report telemetry data is off for content process crashes) - waiting on review (ted)
• bug 1222662 (M8, Mouse cursor disappears after moving it outside the Flash video area) - second patch landed but there's still an issue with single core systems. Need to look at this again and bug 1231944.

• bug 1096804 (M8, Support windows taskbar previews and thumbnails) - addressing review comments from Dao

• M8 bug 1159827 - [e10s] We always show the spinner when closing a tab
  • Unable to reproduce this. Still blocked waiting on STR from billm.
• Perf P1 bug 1221846 - Get Task Tracer working on desktop
  • This builds, and I have Task Tracer samples! Gecko Profiler add-on has been updated to expose this feature as well.
  • Just waiting on one more small review from BenWa, and I can probably land this.
  • There's a processing / symbolication step that I'm missing. The script to do this is very B2G specific. mayhemer is going to work on having Cleopatra symbolicate and display Task Tracer data, aiming for Q1 of 2016.
• Perf P1 bug 1223780 - [e10s][telemetry] regressions in EVENTLOOP_UI_LAG_EXP_MS (3 metrics: parent, children, parent + children)
  • I have a theory that sync messages from the child (for things like screen data, cookies, etc) contribute to this. Looking to prove this today.
• Perf P1 bug 1195295 - content-sessionStore.js sends a sync message to the parent in SyncHandler.init
  • Landed! SessionStore is now CPOW-free. Got a nice talos improvement too.
• bug 1182595 - Make profile dumping work with e10s
  • Have a work-in-progress patch that makes gathering profiles from talos-e10s tests work properly!
  • Have already gathered tpaint profiles - see bug 1174770
• Perf P2 bug 1174770 - tpaint regressions (3%-33%) in e10s mode compared to non-e10s mode
  • I got profiles for this and have a number of leads - the biggest one being the Browser:Init sync message from browser-child.js
  • Expect a wiki page and a video soon
• bug 1225921 - Async tab and window flushing may make it possible to accidentally save tabs we want to forget
  • Fixed.
• bug 1226333 - Add tests for async window flushing
  • Done.

• Reviews for a11y deactivation and e10s experiment on beta
• Test taskforce: working on a list of tests disabled for e10s
• Removing all e10s prompting code
• Hope to start working soon in the e10s beta rollout code

• bug 1173371 - Web page is not shown when launch Firefox from network drive on Windows - thought that I might be able to get this working with with just low integrity, with a view to uplifting printing changes and turning on for Fx45. However it seems that low integrity breaks this as well as USER_INTERACTIVE. Still investigating.
