It's helpful for Mozilla's engineers to be able to measure how Firefox for Android behaves in the real world. The Telemetry feature provides this capability by sending performance and usage info to us. As you use Firefox, Telemetry measures and collects non-personal information, such as memory consumption, responsiveness timing and feature usage. It then sends this information to Mozilla on a daily basis and we use it to make Firefox better for you.

For more about what kind of information is collected and how it's used, see our privacy policy.

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

You can turn this feature on or off at any time in your Settings:

  1. Tap the Menu button (either at the bottom right on some devices or in the upper right of the browser) and then Settings (you may need to tap More first) .
  2. Next tap Mozilla and then check or uncheck the box next to Telemetry in the Data Choices section.
