Faster, more secure, easier to use and sporting a new look, this latest Firefox release sets a new standard for web browser innovation. Mozilla Firefox project (formerly Firebird, which was formerly Phoenix) is a redesign of Mozilla's browser component, written using the XUL user interface language and designed to be cross-platform. It is small, fast and easy to use, and offers many advantages over other web browsers, such as the tabbed browsing and the ability to block pop-up windows.
