Comment (by cypherpunks):

 https://nightly.mozilla.org/ has 64-bit binaries for Windows, but only for
 nightly releases. Building Firefox for Win64 shouldn't be extremely hard
 if Mozilla already does it regularly. However, 64-bit TBB probably is not
 very stable. I'm assuming FF is easy to build, but unstable and buggy,
 which is why it's only a nightly version.

 https://www.openssl.org/about/binaries.html and
 http://slproweb.com/products/Win32OpenSSL.html offer pre-built binaries of
 OpenSSL for Win64. If these can be used for initial testing, that reduces
 the time and effort someone has to spend compiling things. Later testing
 will probably need binaries built on the same machine, though.

 Obviously development time is limited, but running a few initial tests and
 estimating the viability should be easy enough, right? :) I don't have a
 Windows build environment set up, but I can test precompiled binaries on a
 variety of Windows PCs (including Vista, XP, 7, etc.). If someone wants to
 point me in the right direction, I can also get a build environment
 started.

 64-bit Windows is fairly common these days, and I would really enjoy
 having a sped-up 64-bit TBB.

 Post an update to this ticket if volunteers are needed, and I'll get in
 touch with someone.
