One line of code to see heavily downvoted comments

Paste this in your console. It makes every text black.

d=document.getElementsByTagName('font');for(i=0;i<d.length;i++)d[i].color='#000';

Or make it a bookmark...

javascript:(function(){d=document.getElementsByTagName('font');for(i=0;i<d.length;i++)d[i].color='#000';})();
