Photos: Firefox 3 Alpha 5 (Gran Paradiso) 
Published: 13 Jun 2007 07:58 BST
No visible changes (yet)
Opening Gran Paradiso, you'll see almost no changes from Firefox 2. Under the surface, however, is the new Gekko 1.9 rendering engine (Firefox 2 uses Gekko 1.8). Unfortunately, this will mean that Firefox 3 will no longer support Windows 95, 98 and ME; and for the Mac OS X, versions 10.2 and earlier will no longer be supported. There will also be numerous changes made to the Document Object Model (DOM) in Gekko 1.9, which will affect developers more than end users. Also, there will be changes in the way Firefox renders frames within its display and the way object tags are handled, as well as changes in event threading.
