Installation instructions for

Main Debian Repository

We have a Debian repository with which you can easily install and update LibreWolf. To add it to your system and install LibreWolf, run the following commands one by one:

# Change this command to choose a distro manually.
distro=$(if echo " bullseye focal impish jammy uma una vanessa" | grep -q " $(lsb_release -sc) "; then echo $(lsb_release -sc); else echo focal; fi)

wget -O- https://deb.librewolf.net/keyring.gpg | sudo gpg --dearmor -o /usr/share/keyrings/librewolf.gpg

sudo tee /etc/apt/sources.list.d/librewolf.sources << EOF > /dev/null
Types: deb
URIs: https://deb.librewolf.net
Suites: $distro
Components: main
Architectures: amd64
Signed-By: /usr/share/keyrings/librewolf.gpg

sudo apt update

sudo apt install librewolf -y

Attention. We only build LibreWolf for Debian 11, Ubuntu 20/21/22 and Mint 20.2/20.3/21. If you don't use one of those distros, the above commands will install the Ubuntu 20 build for you which may or may not work. If you want to manually choose a different distro's build, then change the first of the above commands to point at that distro. E.g. to install the Debian 11 build, run distro=bullseye.

Also note that we only build for the amd64 (a.k.a. x86_64) architecture. To determine your architecture, run the uname -m command. Most desktop and laptop computers are x86_64; notable exceptions include M1 Macs and Raspberry Pis, as well as very old computers that don't support 64-bit operating systems.

Debian Unstable (unofficial)

There is also an independent and unofficial repository available for Debian Unstable. You can add it to your system and install LibreWolf by running the following commands:

! [ -d /etc/apt/keyrings ] && sudo mkdir -p /etc/apt/keyrings && sudo chmod 755 /etc/apt/keyrings

wget -O- https://download.opensuse.org/repositories/home:/bgstack15:/aftermozilla/Debian_Unstable/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/home_bgstack15_aftermozilla.gpg

sudo tee /etc/apt/sources.list.d/home_bgstack15_aftermozilla.sources << EOF > /dev/null
Types: deb
URIs: https://download.opensuse.org/repositories/home:/bgstack15:/aftermozilla/Debian_Unstable/

You can also download the .deb files of these builds directly from the Open Build Service.
