Waterfox is a high-performance web browser based on Mozilla Firefox’s open-source code, specifically optimized for 64-bit Windows systems. It is designed to deliver maximum speed and efficiency, running faster than a standard 64-bit Firefox build due to advanced compilation optimizations.
This browser is crafted for users who value choice, control, and transparency. Waterfox partners with Ecosia, a search engine that plants trees using its ad revenue, reflecting the browser’s mission to promote sustainability while offering a customizable browsing experience.
Waterfox stands out by offering complete freedom with add-ons and extensions. Users can install any extension without restrictions or plugin whitelists. Privacy is a core focus — the browser sends no telemetry or personal data to Mozilla or the Waterfox project, ensuring a secure and private online experience.
Built on the latest stable Firefox release, Waterfox maintains the same look, feel, and compatibility as Firefox, aside from its branding in the menu bar. This means it offers full functionality while maintaining superior performance and privacy.
Waterfox shares settings, bookmarks, and extensions with Firefox, ensuring smooth coexistence. However, users should avoid deleting personal data during uninstallation if they continue using Firefox. Add-ons remain fully compatible across both browsers, allowing seamless integration and transition between platforms.

What’s new in Waterfox G6.6.3
Fixes and improvements
Theming
- Resolved a long‑standing issue where Waterfox’s styles could “leak” into the web page area. Customizations now apply only to the browser interface, not to website content.
- Improved handling of theme coloring to prevent contrast issues.
Tab groups
- Smoother startup: automatic grouping now waits until your previous session has fully restored. It only applies to tabs you open after everything is loaded.
- Your existing tab order and groups are maintained at startup; nothing is automatically rearranged.
- If you collapse your only tab group, you’ll still have a single ungrouped tab available. That tab won’t be pulled back into a group unless you choose to do so.
Compatibility
- Updated emoji support to Emoji 16.0.1 on platforms that don’t provide these characters natively, improving how newer emojis appear.
Supported Operating Systems:
- Windows 7, 8, 8.1, 10, 11 (64-bit).
- Big Sur 11.0 and above
- Linux glibc 2.17 and above
