A Windows 7 preview in both x86 (32-bit) and x64 versions is also available.
It's unclear how long Mozilla will suspend work, but Smedberg hinted it might be for some time. "It is already a done decision that we aren't going to ship 64-bit Windows Firefox builds in the first half of 2013, and probably not at all in 2013," he wrote in a Nov. 19 message.
Asa Dotzler, director of Firefox, concurred with the plans to discontinue work on x64 Firefox, but noted both that development would likely be restarted in the future and summarized why Mozilla was setting it aside for now.
"I do think we will eventually do a 64-bit release," Dotzler said in a discussion group message last March. "That being said, I don't think it should be a priority right now given the many other things we've got on our plate."
