Fix readability on unreadable pages, typically ones that try to be artsy by using Helvetica as the body font.
var readableStyle = document.createElement("style");
readableStyle.innerHTML = "*,*:before,*:after {font-family:'Lucida Grande',Verdana,sans-serif !important}";
document.head.appendChild(readableStyle);
