Mozilla features fully compliant standards support including HTML 4.0, XML, CSS, and DOM, and is small, fast, and modular. Since its inception, Mozilla has been built using open source, meaning that the source code is publicly available. Mozilla's interface employs the standard browsing paradigm with back, forward, and refresh buttons. It is skinnable, meaning you can download new looks for it. It features the ability to disable unrequested pop-up windows on Web sites. Mozilla also lets you open multiple browser windows and display multiple Web pages in a single tabbed window at the same time. New features in version 1.7 include a new cross-platform NTLM authentication module, security improvements, and crash fixes.
