In Firefox, the Telemetry system collects various measures of Firefox performance, hardware, usage and customizations and submit it to Mozilla. This article provides pointers to documentation.

Getting started

Adding new Telemetry probes is now documented in the Mozilla Source Tree docs.

To discover more Telemetry tools and documentation, visit the Telemetry portal.
