FWIW, I reran a previously-green job and it also started failing, which makes me suspect something external to us changed.

Most likely caused by https://github.com/mozilla-mobile/focus-android/issues/7821

Moving here the other ETP tests disabled for the same reason, so I can close the other issues as duplicates: blockOtherContentTrackersTest blockAdTrackersTest blockAnalyticsTrackersTest
