Theming
Way-back-when, my first introduction to the world of web design was making HTML homepages, CSS overrides, and breaking Windows 10 with custom Explorer themes. I've gotten back into web themes recently, and all the current themes I'm using can be found below.
If you'd like to use these yourself, install Stylish, and copy each theme into a new style.
If you want to use browser CSS themes in Waterfox (or Firefox), follow this guide.
The Discord CSS is there for demonstrative and educational purposes only as, of course, modifying the Discord client is against TOS.
Please note! My philosophy for creating things for my personal use is a nuclear-level bombing of anything that I will not use, that even slightly annoys me, or impairs me from using things how I intend to use it, with this generally becoming more severe the more corporatised the thing I'm using is. Parts will be broken, certain resolutions will not be supported at all, and some functionality will be gutted. If you use these, or use it as a base for your own CSS, I'm happy for that, but make no guarantees that these are usable for anyone but myself. I will not make any edits to these on request.

 - Youtube (WIP)
