Features
LibreWolf does not include telemetry or auto-updating, and certain features are disabled.[9][10][11] 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.[12][6][13] LinuxSecurity noted that LibreWolf may not have full compatibility with some websites.[6]
By default, Firefox Sync is disabled for LibreWolf, though it is possible to enable it in the browser’s settings.[14]
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.[15][16]
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.[6]
In December 2025, the developers stated that they will not support features related to generative AI, and will remove those already present in Firefox.[17]
