:karlt, since you are the author of the regressor, bug 1829054, could you take a look?

[Karl Tomlinson (:karlt)]

"Backfill" is not effective for TV because the particular test does not get run.

Looks like extensions.databaseSchema is meant to change soon after startup or maybe later.

Could the timing be different with the recent conversion to ES modules?

Seems like a candidate for ignorePrefs?

We should add this pref to https://searchfox.org/mozilla-central/rev/fb55a4ee44a9a95d099aa806ca494eb988252ded/testing/mochitest/ignorePrefs.json

The change can be detected if a test runs early in a new profile, by https://searchfox.org/mozilla-central/rev/fb55a4ee44a9a95d099aa806ca494eb988252ded/toolkit/mozapps/extensions/internal/XPIDatabase.jsm#1796

Comment 8

[Rob Wu [:robwu]]

All reported test failures are on Android... I suppose that the TV test is running and doing stuff while the rest of the browser (at least the add-ons part) is still initializing.

I'm going to add the pref to ignorePrefs, and hope that this is the only instance of the issue.

[Rob Wu [:robwu]]

Attachment: Bug 1838233 - Add extensions.databaseSchema to ignorePrefs.json

The extensions.databaseSchema pref is used by the implementation to
track the migration state of the extension database. This is an internal
implementation detail that doesn't affect external behavior, and cannot
be controlled by individual unit tests.

TV / --compare-preferences detects changes in some tests on Android,
without it being actionable. This adds the pref to ignorePrefs.json to
avoid noise.
