Use a 64-Bit PC? Instead of Firefox, Try Waterfox 9.0. Earlier this year I wrote about Pale Moon, a version of Mozilla's popular Firefox browser that's optimized for extra speed on Windows.
Besides its focus on speed, another interesting difference in Pale Moon is that it's available in a 64-bit version, where Firefox is not--at least not with an officially supported release. Users of 64-bit machines also have another option, however, and that's Waterfox, a version of Firefox that's optimized for speed on 64-bit systems. Along with last week's Firefox 9 release, the Waterfox project released version 9.0 of its own software. Ready for a run-down? Social Folders.
