As an aside, I find Quora much easier to read with a sans-serif font: https://imgur.com/jdu9fw4

I use the Stylish Chrome extension with this override for Quora to achieve this:

    html,body,h1,h2,h3,h4,h5,h6,.box_feed,.box_feed div,p,.link.selected,blockquote {
	    font-family:"Tahoma", Sans-serif;
	}
