Betterfox is a Firefox configuration tool that applies privacy, security, and performance tweaks through a user.js settings file.
The tool addresses the challenge of hardening Firefox against tracking and privacy threats while maintaining browser stability and performance. Rather than relying on extensions or third-party code, Betterfox modifies Firefox's built-in about:config preferences directly. The approach is guided by principles of minimalism and the minimum effective dose, removing unnecessary features while enabling Firefox's native speed and security capabilities. The configuration is organized into three conceptual guides: Securefox handles privacy and security without breaking websites, Peskyfox removes distracting UI elements and notifications, and Smoothfox optionally adjusts scrolling behavior. Users download the user.js file, place it in their Firefox profile directory, and optionally review common overrides and hardening options before restarting the browser.
Betterfox suits users who want to strengthen Firefox's privacy posture without installing numerous extensions, and who are comfortable editing configuration files. It works best for everyday browsing rather than specialized use cases requiring particular site compatibility. The project recommends pairing the configuration with an ad blocker and DNS-level protection for comprehensive defense against ads and trackers. Unlike approaches that layer multiple extensions, this tool consolidates settings into a single configuration file, reducing complexity and potential conflicts.
The project maintains active engagement with user issues and pull requests. Documentation is comprehensive, with dedicated wiki pages covering backup procedures, common configuration overrides, and optional hardening steps to guide users through customization. The tool receives regular updates to address Firefox changes and emerging privacy concerns.
