Firefox, a free Web browser developed by the Mozilla Foundation, is used by an estimated 270 million people worldwide. To maintain and improve the Firefox browser, Mozilla depends not only on its team of professional programmers and managers but also on a network of volunteer technologists and enthusiasts—free/libre and open source software (FLOSS) developers—who contribute their expertise. This kind of peer production is unique, not only for its vast scale but also for its combination of structured, hierarchical management and open, collaborative volunteer participation.
