It's helpful for Mozilla's engineers 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.
Accessing Telemetry Data
Aggregate Telemetry data from all submissions can be viewed on the Telemetry dashboard at telemetry.mozilla.org.
Instance Telemetry data (collected in your browser) can be viewed by typing about:telemetry into the Firefox URL bar.
