Per discussion in #a11y-team on slack, we should add a telemetry probe to track if users disable site-specific zoom while using default zoom. This probe will help us decide how to prioritise follow-ups and site-specific zoom bugs (as global zoom is default-on).

>
>1) What questions will you answer with this data?
>
>* This telemetry will help us measure how many users (if any) switch site-specific zoom from on to off given global zoom has landed.
>
>2) Why does Mozilla need to answer these questions?  Are there benefits for users? Do we need this information to address product or business requirements?
>
>* There are existing bugs within our zoom code that surface when a user disables site-specific zoom with global zoom. Because there is no way to disable global zoom (only to default it to 100%, which appears disabled to the user), we'd like to track how many users (if any) are exposed to the bugs that occur when site-specific zoom is disabled. This information will help us prioritise fixing these bugs.
>
>3) What alternative methods did you consider to answer these questions? Why were they not sufficient?
>
>* We first checked if there was existing telemetry for zoom preferences, but there wasn't. The existing accessibility probes also do not cover zoom.
>
>4) Can current instrumentation answer these questions?
>
>* No
>
>5) List all proposed measurements and indicate the category of data collection for each measurement, using the Firefox [data collection categories](https://wiki.mozilla.org/Firefox/Data_Collection) on the Mozilla wiki:
>
><table>
>  <tr>
>    <td>Measurement Description</td>
>    <td>Data Collection Category</td>
>    <td>Tracking Bug #</td>
>  </tr>
>  <tr>
>    <td>Does the user have the browser.zoom.siteSpecific pref enabled?</td>
>    <td>Category 2</td>
>    <td>1590485</td>
>  </tr>
></table>
>
>
>6) How long will this data be collected?
>
>* This is scoped to a time-limited experiment/project until version 78.
>
>7) What populations will you measure?
>
>* Which release channels? ALL
>
>* Which countries? ALL
>
>* Which locales? ALL
>
>8) If this data collection is default on, what is the opt-out mechanism for users?
>
>* The regular Firefox telemetry opt out option.
>
>9) Please provide a general description of how you will analyze this data.
>
>*  We will compare the number of users reported to have disabled site specific zoom to the total number of users and prioritise our site specific zoom bugs accordingly. Likely this will result in comparison to some threashold established within the team.
>
>10) Where do you intend to share the results of your analysis?
>
>* Within the Accessibility team.
>
>11) Is there a third-party tool (i.e. not Telemetry) that you are proposing to use for this data collection?
>
>* No

Request for data collection review form

# Data Review Form 

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

This will be documented in 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? (Note, for data collection not needed for security purposes, Mozilla provides such a control mechanism) Provide details as to the control mechanism available.

This can be disabled by turning off Firefox Telemetry.

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

This is not permanent.

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?

Yes, this will expire in Firefox 78.

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

No.
