Mozilla Firefox is a free, open source, cross-platform, graphical web browser developed by the Mozilla Corporation and hundreds of volunteers. Beginning as a fork of the browser component (Navigator) of the Mozilla Application Suite, Firefox has since become the Mozilla Foundation's main development focus (along with the Thunderbird mail and news client), replacing the Mozilla Suite as the foundation's official main software release. The current version is 3.0 released on June 17th, 2008. The first version of Firefox was released November 9th, 2004 as version 1.6; before that the browser was known as Firebird, and before that, Phoenix.
