I don't know why Mozilla has been so reserved with the Windows x64 version of Firefox. 64-bit FF has been around for Linux for a long time, and those of us who have been using the pre-release builds, dev builds, or unofficial builds have had good results with it for Windows, but it took them YEARS to release it... and now that they have, they're very reticent about it. I don't know what they are waiting for to make it available to people who aren't "in the know."
I switched from Firefox x86 to Pale Moon a long time ago, when PM was still using the Firefox profiles. When they started using their own (like Cyberfox), it was no big deal to copy the data over, but when PM started using its own application GUID, a lot of the addons I won't do without no longer worked. That was when I discovered/switched to Waterfox (and Cyberfox; I tried both and found little difference, other than that CF released updated versions of the browser much quicker).
When Firefox x64 finally made it to the beta channel, I gave that a try instead, and I discovered that in the Peacekeeper benchmark, it outperformed Waterfox (despite Waterfox using the faster Intel compiler, which they tout as an advantage) and Cyberfox (despite them having an Intel-optimized build), and Pale Moon was far behind the three other browsers.
I never had any problems with the beta builds of FF x64 in terms of bugs or general crashiness, and I used them from the first few days they were available. Contrast that to the release version of Firefox (x86), which crashed several times a day because of memory limitations (as revealed by some automatic Firefox restarter addon, which would detect when contiguous memory was getting low and give a warning... if I did not allow it to restart FF, it would always crash soon after that). The "unstable" 64-bit version they were being so cautious about was such a massive improvement over the "stable" release version... I never understood why they were being so slow and tentative with 64-bit, especially since they already had 64-bit in Linux, and I think Mac OSX too.
As far as Australis and Cyberfox... CF simply bundles Classic Theme Restorer, or "CTF" as it is called during installation.
