LibreWolf is a free and open-source web browser, a community-driven fork of Mozilla Firefox, designed with a strong emphasis on user privacy, security, and freedom. It systematically removes all telemetry, data collection, and unnecessary 'phoning home' features found in standard Firefox.

By default, LibreWolf comes with hardened security settings, including features like First-Party Isolation (FPI), disabled WebGL, and built-in privacy extensions such as uBlock Origin, LocalCDN, and ClearURLs. This ensures a private browsing experience out-of-the-box, minimizing digital footprints without requiring extensive manual configuration from the user. It supports all Firefox add-ons and extensions, offering a familiar yet significantly more private and secure alternative.

Due to its strict privacy and security defaults, some websites might not function correctly or might require adjusting site-specific settings. The browser is hardened by default, which may lead to a slightly different user experience compared to a standard Firefox installation.

LibreWolf comes pre-configured with several privacy and security enhancements, including uBlock Origin, LocalCDN, and ClearURLs extensions, along with hardened browser preferences like First-Party Isolation (FPI) and disabled WebGL by default.

While hardened by default, users can further customize LibreWolf's extensive privacy and security settings via about:config or by installing additional add-ons to suit their specific needs.

LibreWolf emerged as a community-driven project dedicated to creating a version of Firefox that prioritizes user privacy and security above all else. It was developed in response to concerns over Firefox's telemetry, default settings, and integration of non-essential features. The project aims to provide a truly independent and user-controlled browsing experience by removing all proprietary components and tracking mechanisms. Its development emphasizes transparency and community contributions, maintaining a close relationship with the upstream Firefox project while diverging on privacy-centric defaults.
