Installation instructions for

Debian, Ubuntu and Mint

Attention. This only works if you use Debian 11, Ubuntu 20/21 or Mint 20.2/20.3. If you don't use one of these distros, see Other Debian based distributions down below.

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:

echo "deb [arch=amd64] http://deb.librewolf.net $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/librewolf.list
sudo wget https://deb.librewolf.net/keyring.gpg -O /etc/apt/trusted.gpg.d/librewolf.gpg
sudo apt update
sudo apt install librewolf -y

Debian Unstable (unofficial)

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

echo 'deb http://download.opensuse.org/repositories/home:/bgstack15:/aftermozilla/Debian_Unstable/ /' | sudo tee /etc/apt/sources.list.d/home:bgstack15:aftermozilla.list
curl -fsSL https://download.opensuse.org/repositories/home:bgstack15:aftermozilla/Debian_Unstable/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_bgstack15_aftermozilla.gpg > /dev/null
sudo apt update
sudo apt install librewolf -y

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

Other Debian based distributions

You can try installing the Ubuntu 20 build from the deb.librewolf.net repository by running the following commands.

echo "deb [arch=amd64] http://deb.librewolf.net focal main" | sudo tee /etc/apt/sources.list.d/librewolf.list
sudo wget https://deb.librewolf.net/keyring.gpg -O /etc/apt/trusted.gpg.d/librewolf.gpg
sudo apt update
sudo apt install librewolf -y

This may or may not work, depending on how close your distribution is to Ubuntu 20. If it doesn't work, you can always use AppImage or Flatpack version of LibreWolf.

Removing the repositories from your system

To remove all of the LibreWolf repositories from your system, run:

sudo rm -f \
/etc/apt/sources.list.d/librewolf.list \
/etc/apt/trusted.gpg.d/librewolf.gpg \
/etc/apt/sources.list.d/home:bgstack15:aftermozilla.list \
/etc/apt/trusted.gpg.d/home_bgstack15_aftermozilla.gpg
