Free Download Mozilla Waterfox (Firefox 64-bit)

Waterfox is a high performance browser based on the Mozilla platform. Made specifically for Windows 64-Bit systems, Waterfox has one thing in mind: speed.

  • What makes Waterfox fast?

    Waterfox is compiled with Intel's C++ Compiler with the following optimisations: Intel's Math Library, SSE3, AVX for supported Intel processors, Profile-Guided Optimisation and the /O3 switch. Customisations to the base code were also made.
    • Do all my add-ons and plugins work?

      Your add-ons/extensions work on any version of Firefox, on any platform! That means they all work with Waterfox. On the other hand, only 64-Bit plugins work with Waterfox and as of now those are: Adobe Flash, Oracle Java and Microsoft Silverlight.
    • I'm missing libiomp5md.dll, libmmd.dll or svml_dispmd.dll

      If for some reason you find yourself missing any of these dynamic libraries, you can install the Intel Redistributable.

      Plug It In


      Adobe Flash Player

      The Adobe Flash Player is software for viewing animations and movies using computer programs such as a web browser. Flash Player is a widely distributed proprietary multimedia and application player created by Macromedia and now developed and distributed by Adobe after its acquisition.

      Oracle Java

      Java is a widely used platform used to deploy portable applications for general use. In practical terms, Java consists of a virtual machine, which must be used to run Java programs, together with a set of libraries needed to allow the use of file systems, networks, graphical interfaces, and so on, from within those programs.

      Microsoft Silverlight

      Microsoft Silverlight is an application framework for writing and running rich Internet applications, with features and purposes similar to those of Adobe Flash. While early versions of Silverlight focused on streaming media, current versions support multimedia, graphics and animation.

    • Reference: Release notes for Firefox 53

    What’s new in Waterfox 53.0?

    • Updated to Firefox 53.0
    • The Git repo now includes the mozilla-release commit history to allow easier merging
    • Delay in macOS release as I’ve lost all of my private keys for my previous Apple Developer ID certs and am awaiting the 5 cert limit to be lifted. I’ve heard this can take a while so will try to push as I can’t make any new Mac 💻 releases without one.
    • NPAPI Plugins and unsigned extensions should still run

    Future Developments

    • Trials are being dont with ffmpeg. I’m planning to add support for every audio/video format that isn’t supported natively on the platform Waterfox is run on and allowing support for more codecs such as HEVC etc on top. The UK doesn’t suffer the same patent issues as the US in releasing software that uses H.26X
    • I’m going through all the 3rd party libraries used by the Mozilla platform to make sure they are updated often instead of waiting for them to eventually get merged into mozilla-release

    What features does Waterfox currently have?

    • Compiled with Clang-cl on Windows, Clang+LLVM on Linux
    • Disabled Encrypted Media Extensions (EME)
    • Disabled Web Runtime (deprecated as of 2015)
    • Removed Pocket
    • Removed Telemetry
    • Removed data collection
    • Removed startup profiling
    • Allow running of all 64-Bit NPAPI plugins
    • Allow running of unsigned extensions
    • Removal of Sponsored Tiles on New Tab Page
    • Addition of Duplicate Tab option (toggle with browser.tabs.duplicateTab, thanks to PandaCodex)
    • Locale selector in about:preferences > General (further improved by PandaCodex)


    • When using a profile shared by Firefox, sponsored tile and snippet URLs may overwrite default Waterfox settings, enabling them again
    • Automatic updates will be delayed by 24 hours to make sure there aren’t any pressing issues before seeding to everyone.
