## Description

This project provides a comprehensive configuration template designed to harden the Firefox browser. By modifying internal preference settings, it enforces a standardized security posture that minimizes telemetry, reduces digital fingerprinting, and limits the exposure of unique data to external web services.

The configuration operates through local preference injection, where users manually integrate a static text file into their browser profile directory. This approach maintains a decoupled security policy that functions entirely offline, ensuring that privacy protections remain under local control without reliance on external synchronization or background processes.

The template balances strict privacy and security requirements with ongoing website functionality. It covers a broad range of browser settings, including the mitigation of web tracking and the systematic reduction of the browser's attack surface. The project is distributed as a plain text file, intended for manual implementation within the local user profile.
