Learn commands to install LibreWolf open source browser on Debian 11 Bullseye Linux using command terminal.

What is LibreWorf?

LibreWolf is an open source browser based on Firefox. This means that you will get the performance and stability of the popular Mozilla browser. Along with this, the main goal of the LibreWolf developers is to provide protection against tracking, fingerprinting techniques along with some other security enhancements. It also aims to remove all telemetry, data collection, and annoyances, as well as disable anti-freedom features such as DRM.

Steps to Install LibreWolf Browser on Debian 11 Bullseye

The steps shown in this tutorial can be used for other versions of Debian 11 and Linux based on it, such as Ubuntu, MX Linux, Linux Mint, POP OS, Elementary OS, etc.

1. Use the Debian 11 update command

Run the common system update command on your Debian 11 to make sure everything is up to date. This will also rebuild the APT package manager cache.

sudo apt update && sudo apt upgrade

2. Add the LibreWolf repository

Unlike Firefox, the LibreWolf browser is not available to be installed using the official Debian 11 repository. Therefore, we have to manually add the one offered by the developers of this browser. Here is the command to follow:

echo "deb [arch=amd64] http://deb.librewolf.net $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/librewolf.list

3. Add a GPG key

To confirm that the packages we get from the LibreWolf official repository are from the genuine source without any modification, also add the signed GPG key for the browser packages by its official developers.

sudo apt install wget -y

sudo wget https://deb.librewolf.net/keyring.gpg -O /etc/apt/trusted.gpg.d/librewolf.gpg

Run the system update again:

sudo apt update -y

4. Install LibreWolf on Debian 11

Once all the above commands are executed on your Debian 11 system, we can proceed to the final installation command to install the LibreWolf browser on our system.

sudo apt install librewolf -y

6. Launch the browser

If the above command was successfully executed on your system, the browser is already installed on your Debian 11 Linux. To run it, go to the application launcher and search for LibreWolf, when its icon appears, click on it to run it.

7. How to update the LibreWolf browser

Well, updating or upgrading the browser version will not be a problem as we have its official repository to install it. Therefore, using the APT package manager and the system update command will also pick up and install any new version available for the browser.

sudo apt update && sudo apt upgrade

8. How to uninstall or remove

There are many situations where we no longer need a particular application on our system. If it’s the same for the LibreWolf browser, then removing it won’t be a problem, go for the following commands.

sudo apt autoremove --purge librewolf

To delete the GPG key and repository:

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
