Gran Paradiso Alpha 1 is an early developer milestone for the next major version of Firefox that is being built on top of the next generation of Mozilla’s layout engine, Gecko 1.9.
While an Alpha version of Firefox 3 (Gran Paradiso) Alpha 1 is available for download, this release is not meant for public consumption, only for testing.

Gecko 1.9 Alpha 1 introduces several new features which can be tested by using Gran Paradiso Alpha 1:

  • Cairo is now being used as the default graphics library, affecting all graphic and text rendering
  • Cocoa Widgets are now used in OS X builds
  • An updated threading model
  • Changes to how web pages are painted
  • New SVG elements and filters, and improved SVG specification compliance

Firefox 3 will no longer support operating systems like Windows 95, 98 and ME or Macintosh OS X 10.2.
