If no major problems crop up, 64-bit will reach the Stable edition of Chrome on Windows with version 37. The Nightly build of 64-bit Firefox on Windows can be downloaded directly from Mozilla's FTP server ( download installer).Ī pair of Firefox derivatives - Pale Moon and Cyberfox - are available in 64-bit editions on Windows. One is available on Mozilla's 'Nightly' build line, analogous to Chrome's Canary, but it has not moved onto the more reliable Aurora channel in the two months since Computerworld last checked on its status. Mozilla, on the other hand, has long had 64-bit versions of Firefox for OS X and Linux, but has yet to push a one for Windows into its prime release channels. Opera Software, the Norwegian browser maker known for its same-named desktop flagship, also offers a 64-bit edition on Windows. Apple's Safari has been 64-bit since 2009's version 4, which launched alongside OS X Snow Leopard, and Microsoft's Internet Explorer has been available in 64-bit even longer, since 2006's IE7.
