I have Windows 7 64-bit. When I downloaded the 64-bit version of FF, it wanted to install in the (x86) directory. What's going on? This description from the FF website isn't exactly clear:
Although Linux, Mac OS X and Windows are released for x86-64 OS platform, officially build by mozilla.org / mozilla.com is still for x86 only. This is native 64 bit coded mozilla (Firefox).
