Start64!Mozilla Firefox has yet to release an optimized edition of the famous web browser for 64-bit Windows. However, users can resort to browsers built by other developers that focus on this aspect.

Last year, we provided you with a comparison review between Firefox 20.0.1, Pale Moon 24.5, Waterfox 28 and Cyberfox 20.0.1 to see which one is better in terms of JavaScript performance, startup time and memory usage, and we came to the conclusion that 32-bit Firefox probably remains the best choice for 64-bit Windows.
