1946275 - Remove or update probes expiring in Firefox 138: CANVAS_FINGERPRINTING_PER_TAB before Gecko version gets increased to 138 on 2025-03-03

Status: RESOLVED DUPLICATE of bug 1946406

(Core :: Privacy: Anti-Tracking, task)

Description

[telemetry-probes]

The following Firefox probes will expire in the next major Firefox nightly release: version 138 [1].

CANVAS_FINGERPRINTING_PER_TAB
FONT_FINGERPRINTING_PER_TAB

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 patch to extend their expiry.

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.

Tracking because every expiring probe should cause a test failure.
