The AUR has librewolf and librewolf-bin packages. The first one compiles Firefox with our patches from source while the latter provides a binary.

With yay:

yay -S librewolf

# alternatively:
yay -S librewolf-bin

Without an AUR helper:

git clone librewolf
cd librewolf
makepkg -si


There is a repository available for Debian Unstable, which can be installed using the .deb file found on the Linux releases page, or from the Open Build Service, where there are also instructions for installing the repository manually.

Note: This is for Debian Unstable only - do not try to install this package on any other branch of Debian or Ubuntu/Mint, or you will have errors about being unable to resolve the dependencies.


See the LibreWolf Gentoo repo.


The LibreWolf AppImages are found here. Choose the file that matches your system’s architecture (most modern computers use x86_64).

Then run

chmod +x LibreWolf-*.AppImage

to make it executable.


Set up Flatpak for your distribution (make sure to enable the flathub repository, as LibreWolf requires several dependencies from there). Then download the LibreWolf Flatpak file from here (choose the file that matches your system’s architecture - most modern computers use x86_64), and install it using

flatpak install LibreWolf-*.flatpak

Compiling from source



The macOS installation process involves running a script that patches a Firefox disk image to create a LibreWolf disk image. The macOS build process doesn’t build Firefox from source yet, but we may try to do that in the future.

git clone --recursive
cd macos

See the LibreWolf macOS repo for more.


There are currently some experimental builds for Windows, which can be found here.

Note: These builds are experimental - expect bugs!
