Waterfox 13.0 now available to download [Updated]

Waterfox | The fastest 64-Bit variant of Firefox!

Waterfox is a 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, it’s compiled with optimizations so that it will run more efficiently and faster than just compiling Firefox as a 64-Bit program. For some people with older systems, the 64-Bit version loads quicker and is much more responsive than the 32-Bit build.

How does it compare to 32-Bit Firefox?
In benchmarks, the 64-Bit variant of Firefox out-performs the 32-Bit variant. Also because this variant is being built specifically for Windows, there might be further performance increases.

Were there any optimisations made?
Yes, Waterfox was compiled with SSE, SSE2, x64 favoring and the following optimisation flags: /Og /Oi /Ot /Oy /Ob2 /Gs /GF /Gy

What's New in Waterfox 13?

  • Compiled with Intel's C++ Compiler using /O3 /QaxAVX /arch:SSE3 /Qparallel /w
  • Implemented Intel's LibM (Math Library)
  • Implemented SSE3 support for all processors and AVX for Intel Sandy Bridge and newer processors
  • Reverted back to jemalloc from tcmalloc in preview releases due to a problem occuring
  • Disabled auto-updates, own method will be implemented in Waterfox.Next
  • Thanks for xunxun1982 for the WebGL crash fix

I've tried Waterfox several times now, and I don't find it performs any better than the regular FireFox.

In fact, I find with Flash based stuff and Java, it performs worst.

I'm thinking this is probably due to the x64 Flash and Java plugins.

I am considering going back to Pale Moon, because as far as I am concerned, Waterfox isn't true x64 like Pale Moon.

How?

Ummmm, Waterfox is a 64-bit browser (verify the 64-bit process yourself via Task Manager) so it's true x64?
