I would just like to add that in my experience, "How to Firefox" is just:

- Download Firefox

- Install uBlock Origin

- Use Firebox

Somehow this blog post makes it seem like adopting Firefox is hard, or overwhelming, or some multi step process, and if you don't do those steps you're effectively downgrading. But really it isn't. It's a browser. Its UX is great. It just... works.

The suggestion that to use it properly you need to customize it to the max is simply flat out wrong.
