Waterfox is a web browser that is designed for privacy and security. It is made for 64-bit processors but runs on ARM devices like smartphones or tablets. It can be found across multiple platforms, including classic desktop systems and recent ones such as Mac OS X/ Linux interfaces. Waterfox provides features that are not available in other browsers, such as private browsing, security settings, and ad blocking. It also has an interface similar to Firefox, making it easy to use. Waterfox is an excellent choice for those who want to maintain their privacy and security online.

In the following tutorial, you will learn how to install Waterfox Browser on Linux Mint 21 LTS series using the command line terminal with tips about maintaining and removing the browser versions.

1. Download the compressed archive from https://www.waterfoxproject.org/downloads You'll get a .bz2 file.
2. Extract it to the location of your choice, keeping the directory structure intact. I chose to extract it to my home.
3. You now have a folder called waterfox. Inside that is a file also called waterfox. Doubleclicking that file will start the browser.
4. It will now offer to import your Firefox data.
5. Set up a menu launcher to that 'waterfox' file so it launches from the menu. Inside one of the folders, in the one called 'browser' and then 'icons', you will find a decent looking icon. It's the one shown below.

Waterfox keeps itself updated; if you open Help => About Waterfox it will tell you which version you're running. As of January 1 2018, the current version is 56.0.1.
