How to Install Waterfox on FunOS

Looking for a privacy-focused and performance-optimized web browser as an alternative to Firefox or Chrome? Waterfox might be just what you need. In this guide, we’ll walk you through the complete steps to install Waterfox on FunOS, from downloading the installation file to integrating it into the system menu. We’ll also cover how to completely uninstall it if needed.

What is Waterfox?

Waterfox is a free and open-source web browser based on Mozilla Firefox. It was initially developed to provide a 64-bit version of Firefox before Mozilla officially supported 64-bit builds. Today, Waterfox focuses on performance, privacy, and customization. It removes telemetry (data collection) features found in Firefox and supports legacy extensions that are no longer compatible with recent Firefox versions.

Waterfox is ideal for users who value a Firefox-like experience but want greater control over privacy and browser behavior.
