Firefox Mobile recently hooked up the same performance data telemetry system used by desktop Firefox. If you use the Nightly version of Firefox Mobile, you can start sending anonymous performance data back to Mozilla. We will use this data to improve future versions of Firefox Mobile.
It’s really easy to use and is completely anonymous. Once you enable the feature, everything happens in the background. To enable, go to the Feedback panel and make sure Send performance data is toggled on.
While you’re there, send us some feedback on Firefox Mobile as well.
