Mozilla 1.0 boasts a Web browser, an e-mail reader and a chat client, as well as a cross-platform toolkit for developing Internet-based applications.
Mozilla's first major public release comes just over a month after the group released the beta version of the software, Mozilla 1.0 Release Candidate 1.
The release has been eagerly awaited by open-source fans who claim that the new browser could give big-name rivals such as MS Internet Explorer and Netscape Navigator a run for their money.
The browser software is powered by the Gecko layout engine, which enables the browser to work as well on devices as it does on desktops.
Mozilla 1.0 is a cross-platform product supporting Windows, Linux and Macintosh versions 8, 9 and OSX operating systems.
The browser suite can be downloaded at www.mozilla.org.
