Where can I find stable 64 bit versions of Firefox to download?

The only link I could find for 64 bit was nightly but I don't want that. There is no 64 bit installer on the official page, no 64 bit under betas, and the FTP doesn't even contain any under firefox/releases. Do they even exist or are they only for future releases?

PS - I don't really know where to ask this since there isn't a proper category that I could find for website questions.

The 32-bit builds will work and are actually faster compared to same 64-bit build currently.

The 64-bit Nightly on Windows are are mainly for to test for breakage as it is possible to break the 32-bit win builds without breaking 64-bit win and same goes other way. In the early days long before Firefox 4.0 it was just Linux that got 64-bit builds and they were mainly for breakage.

The 64-bit win builds are still Tier 2 builds which mean if something breaks or a server for it goes down, it does not have the priority to get working right away like the regular Firefox builds which are Tier 1. https://developer.mozilla.org/en/Supported_build_configurations

It looks like the earliest release to have 64-bit on Windows will be Firefox 12. https://wiki.mozilla.org/Platform/2011-11-22

MSVC 2010 Migration (targeting Gecko 12) - khuey
Builders are ready to go.
Tests are green.
Perf numbers look good.
Client side updater requirements are done.

This was a big part in the steps to have 64-bit builds on Windows.

Wow -___- . That's a long time, but at least I know what to release to look for. Thanks for the explanation.

Yeah it has taken longer than what many users would like as Mac and Linux got 64-bit builds starting at Firefox 4.0

It was Firefox 8.0 originally (at end of June) then a probably at 10.0 (mid August) and now they hope to get it at 12.0

Waterfox is the 64-bit Firefox for Windows and has been around I don't know how long. It works just fine.

Waterfox is just a third-party build that rather then building for self only, hosts it online for others to use.

It has taken longer and more work than originally thought as there is no future Firefox release planned for Win64 build at moment, at least with Firefox 15.0 and newer.
