Here the code which fails: https://dxr.mozilla.org/mozilla-central/rev/b906009d875d1f5d29b0d1252cdb43a9b1a5889c/testing/marionette/harness/marionette_harness/tests/unit/test_switch_window_chrome.py#80-84 > self.assertNotEqual(self.get_selected_tab_index(), second_tab_index) > AssertionError: 1 == 1 The screenshot as part of the report.html file is misleading because it captures the first window, but not the newly created one because the context hasn't been switched yet. Given that we check the tab index, I can only assume that `get_selected_tab_index()` is racy and actually still uses the previously open window and not the newly opened one as most recent window: https://dxr.mozilla.org/mozilla-central/rev/b906009d875d1f5d29b0d1252cdb43a9b1a5889c/testing/marionette/harness/marionette_harness/tests/unit/test_switch_window_content.py#36-70 Maybe it is somewhat related to the same underlying problem as bug 1446293.

(In reply to Henrik Skupin (:whimboo) from comment #22)

Given that we check the tab index, I can only assume that
get_selected_tab_index() is racy and actually still uses the previously
open window and not the newly opened one as most recent window:

We indeed had a race here, which got fixed by Gijs on bug 1506796. So this failure should indeed not happen anymore.
