Waterfox is an open-source web browser based on Mozilla Firefox for 64-bit Windows and OS X systems. It is compiled using the Intel C++ Compiler, and uses Intel's Math Kernel Library, Streaming SIMD Extensions 3 and Advanced Vector Extensions. It is compatible with Firefox add-ons and 64-bit NPAPI browser plug-ins.[1] Waterfox has been developed specifically to take advantage of 64-bit systems, which Firefox does not do so.

Although Firefox outperformed Waterfox in Peacekeeper browser benchmark tests run by TechRepublic in 2012,[2] Waterfox showed a mild improvement over Firefox in tests run by Softpedia in 2014.[3] Benchmarks are also available on the developers website run on the system Waterfox is built on.[4] Waterfox was presented at an event called “Pitch@Palace”[5] at St. James Palace for Prince Andrew, Duke of York.

To date Waterfox has over 5,000,000 downloads, spanning 180 countries.
