:Mardak It starting to look like bug 1383599 is responsible for these serious AWSY perf regressions. Please look over this issue. I've retriggered the perf tests, but the results just started to show up.
It looks like the cause for the regression is that AWSY is running with browser.newtabpage.enabled = false. Where before bug 1383599, it was running as if browser.newtabpage.enabled = true (because the pref wasn't being checked). erahm -> jmaher, does the test need to run with enabled = true, and is this where it's being set: https://searchfox.org/mozilla-central/rev/588d8120aa11738657da93e09a03378bcd1ba8ec/testing/marionette/components/marionette.js#89-94 And should it be flipped to true (just remove it as the default is true) as that's what it's been running with?
Flags: needinfo?(edilee) → needinfo?(jmaher)
I am not sure here and :erahm is on pto for another week. if setting this =True fixes this regression we should do that and then leave a pending issue for :erahm.

Comment on attachment 8957665 [details] Bug 1444404 - Use default (true) value for browser.newtabpage.enabled for testing. https://reviewboard.mozilla.org/r/226586/#review232440 I am not sure what other tests will be affected by this, I suspect quite a few. Have you tested this on all unittests (try -bo -p all -u all)?

This patch made a change to files for automation tooling that targets out-of-tree release channels without the review from a geckodriver/Marionette peer. I’m adding some notes to the relevant files to prevent this from happening in the future as part of bug 1401129. As I understand it browser.newtabpage.enable = false was broken at least since Firefox 56? Do we know about Firefox 55? My assumption is that it we don’t need to add this pref back for Firefox 55 compatibility, but I’d like to check to be sure.
Just checked 55.0.3, and browser.newtabpage.enabled does set the page to be mostly blank for the default old Tiles about:newtab, and activity stream isn't packaged, so browser.newtabpage.activity-stream.enabled does nothing. And in 56.0.2, browser.newtabpage.enabled also shows a mostly blank page for old Tiles about:newtab, and now activity stream is packaged For 57.0.4, activity stream is the default about:newtab, and browser.newtabpage.enabled doesn't do anything there. So the pref was not entirely functional since 57 (although one could trigger the blank by disabling both activity stream and newtabpage).
Thanks for checking, mardak! I don’t think we should have to worry about this for the geckodriver 0.20.0 release.
