Re: Firefox nightly 20.0a1 on Windows 8 64-bit Metro tile missing!
Whoops sorry not sure why I had the 32-bit version posted. There is the 64-bit version linked now.
Not sure about the Metro builds, however there is a chance that the 64-bit central Nightly builds maybe stopped for a while (not discontinued as many articles incorrectly posted) as they are not even officially supported and were mainly for catching regressions/breakage as it is possible to break Win64 builds without breaking the official Win32 builds. Bug#814009 (is a example for reading as bugzilla is not a discussion forum). The Win64 builds are still a work in progress despite what many may think as many are those who think 64-bit is better because it is a bigger number when Win32 builds actually works better on 64-bit Windows currently.
