It's helpful for Mozilla's engineers and decision-makers to be able to measure how Firefox behaves in the real world. The Telemetry feature provides this capability by sending performance and usage info to Mozilla. As you use Firefox, Telemetry measures and collects non-personal information, such as performance, hardware, usage and customizations. It then sends this information to Mozilla on a daily basis and we use it to improve Firefox.
Seeing the Collected Data
- Instance Telemetry data (collected in your browser) can be viewed by typing about:telemetry into the Firefox URL bar.
- Aggregate Telemetry data from all submissions can be viewed on the Telemetry dashboard at telemetry.mozilla.org.
- Arbitrary custom analyses can be done via analysis.telemetry.mozilla.org.
- Different datasets are available for SQL queries in our re:dash instance.
