This project is an independent fork of Firefox, with the primary goals of privacy security and user freedom. It is the community run successor to LibreFox.
LibreWolf uses more than 500 privacy/security/performance settings, patches, LibreWolf-Addons (optional) and is designed to minimize data collection and telemetry as much as possible (updater, crashreporter and Firefox’s integrated addons that don’t respect privacy are removed).
LibreWolf is NOT associated with Mozilla or its products.
- Latest Version of Firefox: LibreWolf is compiled directly from the latest build of Firefox Stable. You will have the the latest features, and security updates.
- Completely Independent Build: LibreWolf uses a completely independent build from Firefox and has its own settings, profile folder and installation path. As a result, it can be installed alongside Firefox or any other browser.
- Settings protection: important settings are enforced/locked within librewolf.cfg and policies.json, those settings cannot be changed by addons/updates/LibreWolf itself or unwanted/accidental manipulation; To change those settings you can easily do it by editing librewolf.cfg and policies.json.
- LibreWolf-addons: set of optional LibreWolf extensions
- Statistics disabled: telemetry and similar functions are disabled
- Tested settings: settings are performance aware
- Recommended and code reviewed addons list
- And much more…
LibreWolf is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
Running LibreWolf on Linux without installationUnlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.
Behold! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the LibreWolf AppImage and make it executable using your file manager or by entering the following commands in a terminal:
chmod +x ./*.AppImage
Then double-click the AppImage in the file manager to open it.
If you want to restrict what LibreWolf can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.
If you would like to update to a new version, simply download the new LibreWolf AppImage.
The LibreWolf AppImage also can be updated using AppImageUpdate. Using this tool, LibreWolf can be updated by downloading only the portions of the AppImage that have actually changed since the last version.
Integrating AppImages into the system
If you would like to have the executable bit set automatically, and would like to see LibreWolf and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.
Note for application authors
Thanks for distributing LibreWolf in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
Pro Tips for further enhancing the LibreWolf AppImage
Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/LibreWolf if you have changed it and would like to see this page updated accordingly.
If you would like to see a donation link for the application here, please include one in the AppStream data.
