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.
