A Preview version of what developers hope will become Firefox 1.0 has been made available for testing.

Versions of the well-like new browser are available for Mac, Windows and Linux.

The developers are asking users to help test the software, and hope for a full release early this week.

Firefox is an award-winning Mozilla-based browser. Features include Popup ad blocking, tabbed browsing, integrated Google search, privacy tools, Bookmarks, Text zooming, and many other handy features.
