I started this approach recently, I also change the theme of those Firefox profiles so I remember to close all windows. It is satisfying to keep things separate, and also quite useful to launch somethings as limited apps in a desktop environment. There are lots of things that could be done better, maybe crowd sourced Android/iOS style permissions per website.
