@h3artbl33d I still have a copy of Comic Mono and Komika Text fonts in my ~/.local/share/fonts/ directory. But I don’t use them for a long time when I come back to those in my X11 GUIs.
I think you'll have to apply the custom styling through a browser extension - should also be possible with adblockers like uBlock Origin. The custom CSS can be found here throughout the day: custom.css.
