 Overview: Having fun on Debian will mean we are installing Testing Branch so we get the latest most awesome software while using BTRFS. To accommodate security deficiencies in Testing we will be using a containerized version of Firefox as the default browser (and using chromium as a secondary browser for occasional emergency use). Snap security is very good, excellent even, and as the web is the main point of entry for malicious things for your install, this should be considered to prevent any issues (please don't complain you don't like snap, make your own arrangement in that case). By default Debian comes with the .deb version of Firefox ESR which is excellent but if there is a security bug in the testing branch there can be a delay before a patch arrives. In addition we will also secure a firewall on the local install (see later on in the guide). Once web is secure and a firewall is on you should be good to go so long as you don't ever run commands you saw on the internet you didn't understand, or that came outside of the official repositories. Don't make the mistake of adding repositories from 3rd parties, these can be very risky and in most cases you can use a different method, like flatpak,snap build from source etc. If you do have to, it probably means you need to log a feature request or bug to improve Debian. Overview: Having fun on Debian will mean we are installing Testing Branch so we get the latest most awesome software while using BTRFS.

 +Note: Two video guides from YT creators showing a differing perspective / alternate view on how to do this is shown here: https://www.youtube.com/watch?v=MoWApyUb5w8 and here (using snapper instead of timeshift): https://www.youtube.com/watch?v=b4vTKg-qW_0

 +Note 2: This guide purposefully leaves @home broken so this can be show, how to fix afterwards. This is crucial if you are not versed in btrfs and snapshots so you can develop an understanding how these subvolumes work, and can be manipulated. If you do understand you should be able to resolve during the setup, the creation of @home yourself. However if you cant complete the steps on your own, then following Step2, then Step3 will bring you into the understanding you need and resolve the @home missing. Its split purposefully over 2 Steps so you can learn and gain a better understanding.
