No Telemetry

Waterfox 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 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 Waterfox 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

Waterfox allows you to modify the internal CSS and JS to your hearts 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.

See the waves Waterfox has mades

The young developer behind web browser Waterfox, which boasts 4m downloads, is now hoping to create a viable rival to Google’s ubiquitous search engine by offering users absolute privacy online.

Alex Kontos has taken on the internet browser behemoths with the creation of Waterfox.

What started out as a teenage hobby in his bedroom is rapidly becoming an influential presence on the internet and a serious rival to the main players.

It’s incredibly difficult for new browsers to penetrate the market, but there’s one such browser called Waterfox, which is attempting to gain a foothold into the market by claiming to be the fastest browser in existence by leveraging on the 64-bit architecture of the latest operating systems.

In a week where we celebrate the best of the British technology industry, we speak to young developer Alex Kontos about building a successful web browser, a search engine that gives money to charity, Microsoft Edge and more.

Alex argues that we need to think hard about the future of the internet.
