A free, open source, graphical Web browser based on Mozilla’s Gecko layout engine and specifically designed for the Mac OS X family of operating systems.
The browser is developed by the Camino Project, a community organization.
In place of an XUL-based user interface used by most Mozilla-based applications, Camino uses Mac-native Cocoa APIs.
Camino does not include an e-mail client or HTML editor; it concentrates on providing “just the browser” in a lightweight application.
