Enjoy the power of Firefox optimised for 64-bit

Waterfox Browser is a web browser based on the Firefox browser engine, specifically designed for 64-bit operating systems. Compared to the standard Firefox browser, Waterfox's advantages include faster browsing speeds, improved handling of large memory and 64-bit computing specifics, leading to enhanced stability and performance. The downside is that it is limited to 64-bit operating systems, meaning plugins must also be compatible with 64-bit systems to function properly within the browser.

Features of Waterfox Browser for Mac

1. Tracking Protection

Waterfox's Enhanced Tracking Protection safeguards your privacy while you browse. It prevents trackers from following you online and collecting data about your browsing habits and interests without interfering with website operations. It also protects you from malicious programs, such as malware that drains your battery.

2. Offline, ML-Supported Translation

With support from the Bergamot project, Waterfox will soon offer offline, client-side translation services powered by machine learning, keeping your reading truly private.

3. Private Browsing

Private browsing doesn't save your browsing data, such as history or cookies, and leaves no trace after you log out. Waterfox also includes Enhanced Tracking Protection, which blocks hidden trackers from collecting your data and slowing down your browsing.

4. No Telemetry

Everything you do in the browser stays with you. We don't need to know. Telemetry is disabled within the browser - only limited data collection is used to keep your browser up-to-date and secure. Read more in the privacy policy.
