M8 bug 1238180 - Unsafe CPOW usage in nsContextMenu.js, browser.js for pageInfo for data URIs opened from context menu
- Fixed, landed on fx-team. This will break Page Info for sidebar browser, but sidebar browser appears to just be busted in general for many things.
M8 bug 1233803 - Get rid of of sessionHistory CPOW sent up via WebNavigation:SetHistory message
- Fixed, landed in mozilla-central, just uplifted to aurora.
M8 bug 1233497 - Make unsafe CPOWs from non-addon browser code throw by default
- We've decided to allow CPOWs within Task.jsm and Promise-backend.jsm for now
- Sent email to dev-platform and firefox-dev about this bug.
- Last Try push, these patches seem to have caused an intermittent to go perma-orange on dt6 (bug 1240044). There's a patch in that bug which I will now test.
Perf P1 bug 1223780 - [e10s][telemetry] regressions in EVENTLOOP_UI_LAG_EXP_MS (3 metrics: parent, children, parent + children)
- vladan argues that we care about that probe from the content process as well before we can close this one out. bug 1235908 makes that work, so I guess the position is to gather more data from the next Telemetry experiment to determine whether or not there's really a problem here.
Perf P1 bug 1195295 - content-sessionStore.js sends a sync message to the parent in SyncHandler.init
- Still waiting on bug 1220517 to get fixed. :ting and :froydnj are discussing potential fixes.

Finished converting newtab tests, waiting for review
Checked in a bunch of other fixed tests (places, search)
Expanded the browser-chrome test-tips page with more details (https://wiki.mozilla.org/Electrolysis/e10s_test_tips)

bug 1240164 (5% Win tpaint/sessionrestore regression caused by bug 1096804) - resolved. turns out taskbar thumbnailing code regresses these tests. we've lived with this in non-e10s since the original code landed. filed follow up {bug|1241537}.
bug 1232181 (M8, Replace plugin windows with static window captures when scrolling) - wip, currently figuring out gfx layer mechanics associated with the plugin layer.

Working on the 45beta experiment
"<kats> rough approximation: http://mzl.la/1ZOODfD - there's issues with scroll snapping, scrolling the sidebar in gmail, windowed flash plugins, a number of issues on HiDPI displays, an RTL bug"

recent test case work
- bug 1221150 - re-enabled a few working cases
- bug 1237713 - fixed this test case but need to circle back to modernize it once I have a better grasp of how to do that.
- bug 1240750 - fixed and modernized
- looking at others to work on per the e10s tests spreadsheet.
keeping up with needInfo's and pre-triage work
