`UX`: Investigate a better default web browser

LibreWolf was alright, but some updates to it rendered some of my modified settings useless for some reason. This is something that I don't like. Also, web performance of it got worse in my experience. I'm thinking about using Secureblue's `hardened-chromium` instead: https://github.com/secureblue/hardened-chromium While it's not the flatpak, which I prefer, it is the web browser which has the best defaults imo (some minor hardening can be softened through persisting config in `/etc/` if needed).
