1656134 - Remove or update probes expiring in Firefox 82: COOKIE_PURGING_*

Status: RESOLVED FIXED

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

Description

[telemetry-probes]

The following Firefox probes will expire in the next major Firefox nightly release: version 82 [1].

COOKIE_PURGING_ORIGINS_PURGED
COOKIE_PURGING_TRACKERS_WITH_USER_INTERACTION
COOKIE_PURGING_TRACKERS_USER_INTERACTION_REMAINING_DAYS
COOKIE_PURGING_DURATION_MS
COOKIE_PURGING_INTERVAL_HOURS

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 #fx-metrics Slack channel or the #telemetry Matrix room at https://chat.mozilla.org/#/room/#telemetry:mozilla.org. We'll give you a hand.

Steve, if we decide to extend the metrics, I'll ask Tim to help create a patch.

Great, thanks for the request.

1) Is there or will there be **documentation** that describes the schema for the ultimate data set in a public, complete, and accurate way?

Yes, in the probe definition files and the [Probe Dictionary](https://probes.telemetry.mozilla.org/).

2) Is there a control mechanism that allows the user to turn the data collection on and off?

Yes, the [Firefox telemetry opt-out](https://support.mozilla.org/en-US/kb/share-data-mozilla-help-improve-firefox).

3) If the request is for permanent data collection, is there someone who will monitor the data over time?

No; temporary collection.

4) Using the **[category system of data types](https://wiki.mozilla.org/Firefox/Data_Collection)** on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 2, interaction data.

5) Is the data collection request for default-on or default-off?

Default-on.

6) Does the instrumentation include the addition of **any *new* identifiers** (whether anonymous or otherwise; e.g., username, random IDs, etc.  See the appendix for more details)?

No.

7) Is the data collection covered by the existing Firefox privacy notice?

Yes.

8) Does there need to be a check-in in the future to determine whether to renew the data?

englehardt is responsible for renewing the collection as necessary.

9) Does the data collection use a third-party collection tool?

No.

Beta/Release Uplift Approval Request

• User impact if declined: This Telemetry is needed in Firefox release to inform the slow rollout of the cookie purging feature that started in Firefox 79. See https://experimenter.services.mozilla.com/experiments/tracker-cookie-purging/. (The probes were accidentally set to pre-release only). If declined for release the rollout will be on hold until the 80 cycle. If declined for beta the rollout will be on hold until the 81 cycle.
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): No user-facing impact. The Telemetry probes have been in nightly/beta for a cycle with no issues.
• String changes made/needed: none
