A day before the scheduled public release of its long-awaited Firefox 2.0 Web browser, the Mozilla Foundation has posted the final versions of the software on its FTP servers in preparation for the public launch.

The official Firefox 2.0 public launch page has not been activated but the new U.S. versions for Windows, Linux and Macintosh are available now, with versions in other languages also available.

Originally, Mozilla had said it would make the new Firefox 2.0 browser available tomorrow. The last preview version of the browser, called Release Candidate 3, was posted for public download last Monday. New features in Firefox 2.0 include built-in antiphishing controls, built-in RSS and XML feed-viewing capabilities and a new in-line spell checker.
