How to Install LibreWolf Browser on Linux Mint 21 LTS


Firefox is a widely used web browser known for its speed, security, and privacy features. However, some users are concerned about the amount of personal data collected by the browser through telemetry. LibreWolf is a fork of Firefox that aims to address these concerns by eliminating telemetry and increasing protection against tracking and fingerprinting techniques. In addition, LibreWolf includes a few security improvements, such as disabling the auto-updating feature and allowing only signed add-ons to be installed. As a result, LibreWolf provides a more privacy-conscious alternative to Firefox that still offers a good user experience.

In the following tutorial, you will learn how to install LibreWolf Browser on Linux Mint 21 LTS release series. The tutorial will describe importing the official repository and gpg key and updating and removing the browser by utilizing the command line terminal.

Update Linux Mint

Before proceeding with the tutorial, ensuring your system is up-to-date with all existing packages is good.

sudo apt update && sudo apt upgrade -y

Install Required Packages

The following dependencies will need to be installed to install LibreWolf successfully. Most of these packages are already on your system, but running the command can help ensure they’re installed.

sudo apt install wget apt-transport-https gnupg2 -y

If you skip and encounter issues, return and just run the command.


Install LibreWolf Browser

The first step is to import the GPG key to verify the authenticity of the packages. In your terminal, execute the following command to import to your keychain.

sudo wget -O- | gpg --dearmor | sudo tee /usr/share/keyrings/librewolf.gpg

Next, import the LibreWolf repository.

echo deb [arch=amd64 signed-by=/usr/share/keyrings/librewolf.gpg] jammy main | sudo tee /etc/apt/sources.list.d/librewolf.list

Now run an APT update to reflect the newly imported repository.

sudo apt update

Finally, you can install the LibreWolf browser using the following command.

sudo apt install librewolf -y

Launch LibreWolf Browser

Now that you have the privacy-focused browser installed, launching can be done in a few ways.

Using the command line terminal, you can open the browser quickly by using the following command.



The best way to use LibreWolf for desktop users that prefer not to use the command line terminal is to open the GUI of the application by following the path.

Taskbar > Internet > LibreWolf


Next, you will see the default LibreWolf window, similar to Firefox as you would expect but very stripped back.



How to Update/Upgrade LibreWolf Browser

The browser should update itself with your system packages for desktop users using the APT package manager. For users who want to check manually, use the following command in your terminal.


sudo apt update && sudo apt upgrade

How to Remove (Uninstall) LibreWolf Browser

When you no longer want the browser installed on your system, use the following command to remove it.

sudo apt autoremove librewolf --purge -y

Remove the repository if you plan not to re-install LibreWolf again.

sudo rm /etc/apt/sources.list.d/librewolf.list

After removing the repository list file, remove the GPG.

sudo rm /usr/share/keyrings/librewolf.gpg

Comments and Conclusion
