Firefox sends various data back to Mozilla. This data keeps the browser up to date, powers various features, provides user support, and helps improve the product itself. This page documents the policy for how and why we add new data collection metrics. The owner and peers of the Firefox Data Collection policy module are responsible for making decisions about data collection systems and measurements.
Function:
* is Is the data collection necessary for Firefox to function properly? For example, the automatic update check must be sent in order to keep Firefox up to date.
* Is there a specific user-visible function planned for the data?
* Population: Is it necessary to take a measurement from all users? Or is it sufficient to measure only prerelease users?
Analysis and Reporting:
* who Who will be analyzing the data?
* Will the data that's being collected answer the questions we have?
* Will it be a single or periodic report?
== Requesting Approval ==
It is our intention to review every new data collection within Firefox, but to do so quickly and with minimal overhead. For every new measurement, even a simple new Telemetry probe, please request approval by setting the NEEDINFO feedback flag for the module owner or a peer. Simple requests should be handled within a day.
More complex requests, and especially requests which add a new kind of data collection mechanism or require changes to the privacy notice, will require more extensive review. Please consider pinging the team about these as they are being designed! Additional discussions/review may include:
