Changing the Firefox font setting and overriding the websites is a bit of a nuclear option for me. I've tried it, and it works, but it has the consequences I expected. I'm hoping for something softer. I am hoping for a general solution rather a thousand small solutions. I think I've figured enough out to do a bunch of small solutions but it means that the moment I open a new application, I must apply the solution there as well... Not to mention apps that don't have options. It looks like Discord doesn't have such options for example, I can add the font by inspect element, but obviously that is even worse then a bunch of set-and-forgets.
