Send performance data to Mozilla to help improve Firefox
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 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.
How do I opt-in or opt-out of sending performance data?
When you install or update Firefox you may be presented with the following message that lets you turn the Telemetry feature on:
"Will you help improve Mozilla Firefox by sending information about performance, hardware, usage, and customizations to Mozilla?"
You can also turn this on and off at any time with these steps:
- At the top of the Firefox window, click on the button and then select At the top of the Firefox window, click on the menu and then select On the menu bar, click on the menu and select At the top of the Firefox window, click on the menu and select

- Select the tab.
