Learn commands to install LibreWolf open source browser on Ubuntu 20.04 Focal Fossa LTS 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 Ubuntu 20.04

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

1. Use Ubuntu Update Command

Run the common system update command on your Ubuntu 20.04 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 install using the official Ubuntu 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 Ubuntu 20.04 LTS Focal

Once all the above commands are executed on your Ubuntu 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, then the browser is already installed on your Ubuntu 20.04 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
