Font blocker for Chrome

I’ve been playing with my fonts settings for a while and I am close to getting nuts. I have almost everything the way I want it, however, some web-pages insist on using their own fonts. Twitter with it’s Chirp font and GitLab with their own font family come to mind. Well, I don’t like it, do I tried to find a solution.

I searched a bit and came across the Font blocker extension for Google Chrome. Install it, then right click on the annoying font you want to block. Clicking on its Options will get you a list of fonts replacements. That’s it.
