64 bit version of Firefox 4.0 for Windows 7 and Vista is now available for download. This is the first time Mozilla have launched x64 version of Firefox that can run on 64 bit Windows 7 and Vista. Prior to that, only Internet Explorer supports 64 bit OS versions but now Mozilla have also joined in with their newly launched Firefox 4.0. This is pre alpha release of the browser though but should work well. Download filename “Firefox-3.7a5pre.en-US.win64-x86_64” is bit confusing though as it includes Firefox 3.7 but it actually is Firefox 4.0 in disguise.

Firefox 4.0 64 bit can be downloaded from Mozilla FTP servers.
