Waterfox is high performance 64-Bit 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, its compiled with optimizations so that it will run more efficiently and faster than just compiling Firefox as a 64-Bit program.
