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]

Full builds run on Open Build Service. ^[5]

Development

LibreWolf was initially released for Linux operating systems on March 7, 2020. ^[6] The goal of the LibreWolf project was to create a more privacy-focused version of Firefox. ^[7] A community-maintained version for Windows was released a year later, with a macOS port released soon after. ^{[8] [9]}

Features

LibreWolf does not include telemetry or auto-updating, and certain features like Pocket are disabled. ^{[10] [11] [12]} 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. ^{[13] [7] [14]} LinuxSecurity noted that LibreWolf may not have full compatibility with some websites. ^[7]

By default, Firefox Sync is disabled for LibreWolf, though it is possible to enable it in the browser's settings. ^[15]

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. ^{[16] [17]}
