I had a huge page that was killing Firefox with an out of memory exception (that was a few years ago). Googled for 64 bit Firefox and got Waterfox, which solved that problem. So that's another selling point.
As of version 42, 64-bit Firefox is available on all tier-1 desktop platforms (Linux+GTK, Mac, Windows).
