LibreWolf is a free and open-source fork of Firefox, with an emphasis on privacy and security. [1] [2] [3] It is licensed under the MPL 2.0. [4]
LibreWolf was initially released for Linux operating systems on March 7, 2020. [5] The goal of the LibreWolf project was to create a more privacy-focused version of Firefox. [6] A community-maintained version for Windows was released a year later, with a macOS port released soon after. [7] [8]
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]
As there seems to have been recent confusion about this, just a quick "official" toot to then pin: we haven't and won't support "generative AI" related stuff in LibreWolf. If you see some features like that (like Perplexity search recently, or the link preview feature now) it is solely because it "slipped through". As soon as we become aware of something like this / it gets reported to us, we will remove/disable it ASAP.
