Waterfox is a free, open-source web browser and fork of Mozilla Firefox that’s built for users who prioritize privacy, performance, and customizability while still maintaining compatibility with modern web standards and extensions. It began as a 64-bit-focused fork and has grown into a full-featured browser available on Windows, macOS, Linux, and Android, making it a versatile alternative to mainstream browsers. Waterfox removes or disables much of Firefox’s telemetry and unnecessary data collection by default, giving users greater control over what is shared with third parties while still supporting classic and modern add-ons. The project emphasizes speed and efficiency through optimizations and choice, letting users tweak settings or install favored extensions without being locked into ecosystem constraints. Because it’s open source and actively developed by the community, new features, security updates, and performance improvements arrive regularly to align with web standards.
