1725297 - Remove or update probes expiring in Firefox 94: BASE_FONT_FAMILIES_PER_PAGE

Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, task)

Description

[telemetry-probes]

The following Firefox probes will expire in the next major Firefox nightly release: version 94 [1].

BASE_FONT_FAMILIES_PER_PAGE
LANGPACK_FONT_FAMILIES_PER_PAGE
USER_FONT_FAMILIES_PER_PAGE
WEB_FONT_FAMILIES_PER_PAGE
FALLBACK_TO_PREFS_FONT
FALLBACK_TO_BASE_FONT
FALLBACK_TO_LANGPACK_FONT
FALLBACK_TO_USER_FONT
MISSING_FONT
MISSING_FONT_LANGPACK
MISSING_FONT_USER

What to do about this:

1. If one, some, or all of the metrics are no longer needed, please remove them from their definitions files (Histograms.json, Scalars.yaml, Events.yaml).
2. If one, some, or all of the metrics are still required, please submit a Data Collection Review [2] and patch to extend their expiry. There is a shorter form for data collection renewal [3].

If you have any problems, please ask for help on the #data-help Slack channel or the #telemetry Matrix room at https://chat.mozilla.org/#/room/#telemetry:mozilla.org. We'll give you a hand.

I don't think these probes are really telling us anything interesting at this point, we can just remove them.

(We may want some related telemetry again as and when we deploy anti-font-fingerprinting measures, but I expect we'll want a somewhat different set of probes. So for now let's just drop these, which also lets us remove the FontMatchingStats record that we pass around a lot of places.)
