Here some exact steps:

1. Open [test_navigation.py](https://searchfox.org/mozilla-central/source/testing/marionette/harness/marionette_harness/tests/unit/test_navigation.py#186) in your editor
2. Replace all `def test_` with `def tst_` except for `test_frameset`
3. Run `mach marionette-test --gecko-log - -vv testing/marionette/harness/marionette_harness/tests/unit/test_navigation.py --enable-fission --setpref fission.bfcachInParent=tue --repeat-until-failure`

Usually the failure happens after around the 10th iteration for a Linux opt artifact build.
