Running Windows 7 64 bit on the newish Draper home made superputer,so decided to google for a 64 bit browser if such a critter existed and downloaded Mozilla Nightly? is this actually a 64 bit browser?,it don't seem any faster than the Win Explora I am also running, though in truth I do not know what version of Win Explora I am running, perchance it is the 64 bit version as well?
