WaterFox -> The 64bit version of FireFox web browser
Waterfox is basically a 64-Bit (x64) version of Firefox. The Firefox source code is taken and compiled to run specifically for 64-Bit Windows computers. To make Waterfox stand out a bit more, it’s compiled with optimizations so that it will run more efficiently and faster than just compiling Firefox as a 64-Bit program.
Download waterfox 8.0 -> http://waterfoxproj.sourceforge.net/downloads
Run time required for running WaterFor
- Download Microsoft Visual C++ 2010 Redistributable Package (x64)
- Adobe Flash Player x64 -> http://get.adobe.com/flashplayer/
- Sun JAVA Run time x64 -> http://www.java.com/en/download/windows-64bit.jsp
- Microsoft Silverlight x64

Why going x64 ?
With compatible platform (Windows x64 and x64 platform processor) this specific build has performance advantage with faster loading time and browsing experiences.

I used Palemoon that is faster than original firefox. I can not try Waterfox as I do not have 64bit PC!
