Waterfox Classic provides you with a high-performance browser 64-Bit version of Mozilla Firefox. The Firefox source code was taken and compiled in order to specifically run for 64-Bit Windows computers. To make Waterfox Current stand out from the crowd, it’ was compiled with many optimizations so that it will perform faster and more efficiently than simply compiling Firefox as a 64-Bit program.

Use this version of the app if you have your browser set up with various NPAPI plugins and bootstrap extensions that have not been updated as WebExtensions or for Waterfox Current.

Features and Highlights

No Telemetry
It does not collect any telemetry, meaning you do not have to worry about any tracking or usage information about what you do inside your browser.

Limited Data Collection
The only thing that Waterfox Classic sends back is your OS and browser version to check for updates to various components. That's it, and no more.

NPAPI Plugins
They should be used responsibly, but the browser supports the use of Java and Silverlight plugins, as well as any other 64-Bit NPAPI plugins.

Bootstrapped add-ons
Waterfox is one of the few fully customizable browsers, allowing you to modify and extend it any way you please. From WebExtensions to classic-style bootstrap add-ons. You'll even find some of your favorites already updated such as DownThemAll!, Greasemonkey, Private Tab, and more!

Polish your userChrome
It allows you to modify the internal CSS and JS to your heart's content, no need to worry about it being dropped in functionality!

Stable API
No need to worry about your extensions becoming obsolete every release, with a stable API until the next major release milestone.

Add-ons are like apps that you install to add features to the browser. They let you compare prices, check the weather, listen to music, send a tweet, and more.

Make Waterfox Classic match your style. Choose from thousands of themes and dress up your web browser with a single click.
