LibreWolf is a free and open-source fork of Firefox, with an emphasis on privacy and security. It is licensed under the MPL 2.0.
Development LibreWolf was initially released for Linux-based desktop operating systems on March 7, 2020. The goal of the LibreWolf project was to create a more privacy-focused version of Firefox. A community-maintained version for Windows was released a year later, with a macOS port released soon after.
Features LibreWolf does not include telemetry. Certain features such as auto-updating and WebGL are disabled by default . It does not have sponsored shortcuts.
By default, LibreWolf deletes the user’s cookies and history when the browser is closed, but that feature can be disabled. LinuxSecurity noted that LibreWolf may not have full compatibility with some websites.
By default, Firefox Sync is disabled for LibreWolf, though it is possible to enable it in the browser’s settings.
According to the website PrivacyTests.org in 2022, LibreWolf, along with Brave Browser and Tor Browser, had the most privacy protection compared to other browsers.
In most cases, LibreWolf was found to have similar performance to Firefox; however, LibreWolf's stronger focus on privacy and security features may slightly impact web optimization.
In December 2025, the developers stated that they will not support features related to generative AI, and will remove those already present in Firefox.
