Mozilla is a nonprofit project and global community building a better internet. Mozilla Stumbler is an open-source wireless network scanner that collects GPS data for the Mozilla Location Service, our crowd-sourced location database. As you move around, the app "stumbles" upon new Wi-Fi networks and cell towers. The Mozilla Location Service combines these wireless network measurements to provide geolocation services for Firefox OS devices and other open source projects.
