How to Install LibreWolf Browser on Ubuntu 20.04 LTS | #linux | #linuxsecurity | #hacking | #aihp

Learn the commands to install open source LibreWolf 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 you will get the performance and stability of the popular Mozilla browser. Along with that, the key focus of the LibreWolf developers is to provide protection against tracking, fingerprinting techniques along with other few security improvements. It also aims to remove all the telemetry, data collection, and annoyances, as well as disabling anti-freedom features like DRM.

Steps to install LibreWolf browser on Ubuntu 20.04

Steps given in this tutorial can be used for other versions of Ubuntu, and Linux based on Debian such as MX Linux, Linux Mint, POP OS, Elementary OS, and more…

1. Use Ubuntu Update Command

Execute the common system update command on your Ubuntu 20.04 to ensure everything is up to date. This will also rebuild the APT package manager’s cache.

sudo apt update && sudo apt upgrade


2. Add LibreWolf Repository

Unlike Firefox, the LibreWolf browser is not available to install using the official repository of Ubuntu. Hence, we have to manually add the one offered by the developers of this browser. Here is the command to follow:

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


3. Add GPG Key

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

sudo apt install wget -y
sudo wget -O /etc/apt/trusted.gpg.d/librewolf.gpg

Run 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 go for 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 has been executed on your system successfully, then you would already have the browser installed on your Ubuntu 20.04 Linux. To run it, go to the Application launcher and search for LibreWolf, as its icon appears, click the same to run.


7. How to update the LibreWolf browser

Well, updating or upgrading the browser version will not be an issue because we have its official repository to install it. Hence, using the APT package manager and system update command will also fetch and install any new version available for the browser as well.

sudo apt update && sudo apt upgrade


8. How to uninstall or remove

There are many situations where we don’t require any particular application on our system anymore. If the same is for the LibreWolf browser, then removing it will not be an issue, go for the following commands.

sudo apt autoremove --purge librewolf

To remove 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 \
