64-bit FF2, also known as "Bon Echo" can be downloaded from
here. Been using it for a while now, and it seems a little snappier - but I think the major advantage is better security against spyware and all that mumbo jumbo.
It's self extracting but doesn't create icons, so you can install it away from your x86 FF and it won't effect it. It'll simply read your normal profile and
should load it without any troubles
