The Mozilla Foundation recently released <A HREF="http://www.eweek.com/article2/0,1895,2071031,00.asp?kc=EWEWEMNL121106EP23C">the first alpha of Firefox 3.0,</A> and when people refer to this release of the browser as a developer version, they aren't kidding. In fact, the only difference that a regular Firefox user will notice between this alpha and the current shipping version of Firefox 2.0 is that the top browser title bar and the About screens use the Firefox 3.0 code name Gran Paradiso instead of Firefox. But while this alpha release has no interface changes, there are some fairly important changes in the underlying engine of the browser. Gran Paradiso is also an alpha of Gecko 1.9, the forthcoming rendering engine for Mozilla browsers.
