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 (Do not use this on any other release of Debian)

echo 'deb /' | sudo tee /etc/apt/sources.list.d/home:bgstack15:aftermozilla.list
# make sure you have curl installed
curl -fsSL | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_bgstack15_aftermozilla.gpg > /dev/null
sudo apt update
sudo apt install librewolf

See the repository for more details, and the option to use a .deb file instead of these commands.


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!
