Where is the 64-bit version of the Firefox web browser for the Windows operating system? That’s a question that I have been asking myself for the past couple of years, probably ever since I updated to a 64-bit version of Windows 7 Professional. Mozilla is offering 64-bit versions of the browser for Mac and Linux, but Windows, the operating system that is used by the majority of Internet users? There have been nightly and custom builds of 64-bit versions of Firefox, but that is about it.
64-bit versions have been in development for quite some time, a roadmap released in 2011 for instance lists the Windows 64-bit version of Firefox under Firefox 5. That did not happen but still, most Firefox users probably expected that Mozilla would eventually release Firefox 64-bit for Windows.
That dream may have been shattered now with the announcement that Mozilla decided to stop producing 64-bit builds for the Windows operating system.
