Comment on attachment 9038380 [details] Data review request Preliminary notes: The collection request is until Firefox 72, but the definition in the patch is only until 68.

DATA COLLECTION REVIEW RESPONSE: Is there or will there be documentation that describes the schema for the ultimate data set available publicly, complete and accurate? Yes. This collection is Telemetry so is documented in its definitions file ([Scalars.yaml](https://hg.mozilla.org/mozilla-central/file/tip/toolkit/components/telemetry/Scalars.yaml)), the [Probe Dictionary](https://telemetry.mozilla.org/probe-dictionary/), and on telemetry.mozilla.org's [Measurement Dashboards](https://telemetry.mozilla.org/new-pipeline/dist.html). Is there a control mechanism that allows the user to turn the data collection on and off? Yes. This collection is Telemetry so can be controlled through Firefox's Preferences. If the request is for permanent data collection, is there someone who will monitor the data over time? N/A, expires in Firefox 72. Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under? Category 1, Technical. Is the data collection request for default-on or default-off? Default on for all channels. Does the instrumentation include the addition of any new identifiers? No. Is the data collection covered by the existing Firefox privacy notice? Yes. Does there need to be a check-in in the future to determine whether to renew the data? Yes. :alwu is responsible for renewing or removing this collection before it expires in Firefox 72. --- Result: datareview+
