.includes is still nightly-only. Please fix ASAP given where we are in the cycle. https://treeherder.mozilla.org/logviewer.html#?job_id=10214803&repo=try 21:45:24 INFO - 646 INFO TEST-UNEXPECTED-FAIL | browser/base/content/test/general/browser_urlbar_autoFill_backspaced.js | Uncaught exception - at chrome://mochitests/content/browser/browser/base/content/test/general/browser_urlbar_autoFill_backspaced.js:24 - TypeError: types.includes is not a function

I'll fix this today since Marco's away.

This is consistently hitting a new error now: https://treeherder.mozilla.org/logviewer.html#?job_id=10247289&repo=try 707 INFO TEST-UNEXPECTED-FAIL | browser/base/content/test/general/browser_urlbar_autoFill_backspaced.js | A promise chain failed to handle a rejection: - at chrome://mochikit/content/browser-test.js:752 - TypeError: this.SimpleTest.isExpectingUncaughtException is not a function

The failure seems to be caused by browser_urlbarSearchSuggestionsNotification.js 20:33:55 INFO - 649 INFO TEST-START | browser/base/content/test/general/browser_urlbar_autoFill_backspaced.js 20:33:56 INFO - ************************* 20:33:56 INFO - A coding exception was thrown and uncaught in a Task. 20:33:56 INFO - Full message: TypeError: Assert is null 20:33:56 INFO - Full stack: focus_allSuggestionsDisabled@chrome://mochitests/content/browser/browser/base/content/test/general/browser_urlbarSearchSuggestionsNotification.js:33:3 I don't think this should be reopened, it's clear a previous test is causing this one to fail.

OK, thanks for checking.
