When this first got posted I wasn't experiencing the problem. But now I've noticed that when I bring up Amazon in FF under Win7Pro, all running 64-bit, latest versions, etc., I can consistently get the video driver to crash. Very reproducible problem. There is either some component trying to load on their website, or some feature that the graphics hardware can't handle under FF+Win7Pro. Problem doesn't exist using Chrome, or even FF in Linux.
