Firahub 作者： Dante Falzone

This extension changes the monospace font on Github.com to Fira Code. I wrote this because the other guy's extension doesn't work.

Source code:

var elements = document.getElementsByClassName('blob-code');
for (var i in elements) {
    elements[i].style.fontFamily = "Fira Code Retina,Fira Code,monospace";
}
