Waterfox 是一個依據 Firefox 來最佳化的64位元版本，Waterfox 參數經過最佳化調整，堪稱網頁載入的速度比火狐還要快，而且不輸給Google的Chrome瀏覽器。

Waterfox was one of the first widely distributed 64-Bit browsers on the web and quickly gained a loyal following. At a time Waterfox had one thing in mind: speed, but now Waterfox also attempts to be an ethical, user-oriented browser.

Waterfox focuses on giving users choice while also helping make the world a better place. Waterfox is partners with Ecosia, a search engine that plants trees with its generated revenues. The browser itself is focused on power users, which lets you make the important decisions. There is no plugin whitelist, you can run whichever extensions you like and absolutely no data or telemetry is sent back to Mozilla or the Waterfox project.
