Telemetry is an opt-in feature. This means that you specifically need to tell Firefox to collect and send this information to Mozilla. For more about what kind of information is collected and how it's used, see Mozilla's Firefox Browser Privacy Notice.

You can turn this on and off at any time with these steps:
- In the Menu bar at the top of the screen, click and then select or , depending on your macOS version.Click the menu button
