It is often beneficial to be able to measure how software behaves in the real world. Telemetry provides this capability for the Firefox browser by sending performance data to Mozilla so we can identify where Firefox could be better. As you use the software, Telemetry measures and collects non personal data from your browser, such as memory consumption, responsiveness timing, and feature usage, and then sends it to Mozilla on a daily basis. Telemetry is an opt-in solution. This means that you specifically need to instruct Firefox to send this data. For more information about what kind of data is collected and how it's used, see

How do I opt-in or opt-out of sending performance data?
