Waterfox is a privacy-focused web browser that emphasizes speed, control, and privacy. It was one of the first widely distributed 64-bit browsers and quickly gained a loyal following. Initially focused on speed, Waterfox now also aims to be an ethical, user-oriented browser, striking a balance between privacy and usability. Here are some key features:

1. Privacy Out of the Box: Waterfox comes with built-in tracking protection and Oblivious DNS, making it harder for ISPs to track your website connections.
2. Private Tabs with Private Search: You can browse privately and anonymously within a private tab without opening a separate private window.
3. Container Tabs: Organize your browsing by separating work, shopping, or personal activities using different container tabs.
4. Data Privacy: Waterfox doesn't collect your data, and telemetry is disabled within the browser. Limited data collection ensures your browser stays up to date and secure.
5. Compatibility: Waterfox supports Firefox add-ons and is compatible with Google Chrome and Opera extensions.
