Waterfox is a Windows browser whose name already sounds familiar—because it’s a high-performance fork of Mozilla Firefox. Built exclusively for 64-bit systems and compiled with Intel’s C++ compiler, Waterfox delivers Firefox-level compatibility at noticeably higher speed while putting privacy first. No telemetry, no data harvesting—only you know what you do online.
Switch instantly between Bing, Google, Wikipedia, Yahoo, Yandex, Qwant and Ecosia; sync bookmarks, manage passwords, install any Firefox add-on and apply custom themes. Every feature is optimized for 64-bit Windows, so pages load faster and heavy extensions run smoother. If you want Firefox freedom without the phoning-home, Waterfox is the browser to beat.
What is Waterfox?
Waterfox is the most stable 64-bit Windows build based on official Firefox source code. Large-memory and 64-bit CPU optimizations make it quicker and more responsive than standard Firefox on compatible hardware.
Before You Install
You need the Visual C++ 2010 runtime plus 64-bit versions of Flash, Silverlight and Java for the full web experience (32- and 64-bit plugins are not interchangeable).
