Available Web browser Librewolf 94 , which is a rebeling of Firefox 94 with changes aimed at improving security and confidentiality. The project develops by the community enthusiasts. Changes published under the MPL 2.0 license (Mozilla Public License). Build formed for Linux (Debian, Fedora, Gentoo, Ubuntu, Arch, Flatpak, Appimage), MacOS and Windows. Among the main differences from Firefox:
- Removing the code associated with the transfer of telemetry, conducting experiments to enable test capabilities in part of users, showing advertising inserts in recommendations when typing in the address bar, output of unnecessary ads. Any appeals to the Mozilla servers are disabled if possible and the installation of background connections is minimized. Removed built-in add-ons to check updates, sending reports about collaps and integration with the Pocket service.
- Using the default search engines that save confidentiality and non-tracking user preferences. There is support for search engines DuckDuckGo, SEARX and QWant.
- Inclusion in the basic supply of Ublock Origin advertising blocker.
- The presence of a firewall for additions that limits the ability to install network connections from additions.
- accounting for the developed project arkenfox recommendations for strengthening confidentiality and security, as well as blocking opportunities to carry out the passive identification of the browser.
- Enabling optional settings, resulting in improving performance.
- Operational Formation of Updates based on the basic Firefox code base (build of new librewolf issues are formed within a few days after the release of Firefox).
- Disable the default proprietary components to view the protected DRM content (Digital Right Management). To block indirect methods of user identification, WebGL is disabled by default. Also, the default IPv6, WebrTc, Google Safe Browsing, OCSP, API GEO Location are disabled.
- Independent Assembly System – Unlike some similar projects, LibreWolf generates assembly independently, and does not make corrections to the ready-made Firefox assemblies and does not replace the settings. Librewolf is not associated with the Firefox profile and is installed in a separate directory, which allows you to use it in parallel with Firefox.
- Protection of important settings from change. Configuring security and confidential settings are recorded in librewolf.cfg and policies.json files, and cannot be changed from additions, updates or browser itself. The only way to make changes is direct editing files librewolf.cfg and policies.json.
- optionally proposed a set of verified Librewolf-Addons addons, which includes additions such as noscript
/Media reports.
