Kill Sticky Headers. You know, those stupid f-ing "hover toolbars" and shit that is so in vogue with web designers these day? The ones that cover up the things you are actually trying to read? This will kill those, just drag the button to your toolbar where it will create a bookmarklet. I use a similar one called PopStopper and it's invaluable.

Popstopper is just a bookmark with the following:

javascript:(function(){var%20e=document.body.style.cursor;document.body.style.cursor="crosshair";var%20t=document.createElement("div");var%20n="border:1px%20solid%20#3280FF;background-color:rgba(50,128,255,0.5);position:absolute;z-index:999999999999999;display:none;";var%20r="pointer-events:none;";var%20i="transition:width%2060ms,height%2060ms,left%2060ms,top%2060ms;";n+=r+"-webkit-"+r+"-moz-"+r;n+=i+"-webkit-"+i+"-moz-"+i;t.setAttribute("style",n);document.body.appendChild(t);var%20s=null;var%20o=function(e){var%20n=e.target;if(n!==s&&n.parentNode){var%20r=n.getBoundingClientRect();var%20i=document.documentElement;var%20o=document.body;var%20u=i.clientTop||o.clientTop||0;var%20a=i.clientLeft||o.clientLeft||0;var%20f=window.pageYOffset||i.scrollTop||o.scrollTop;var%20l=window.pageXOffset||i.scrollLeft||o.scrollLeft;var%20c=l-a+r.left-1;var%20h=f-u+r.top-1;t.style.display="block";t.style.left=c+"px";t.style.top=h+"px";t.style.width=r.width+"px";t.style.height=r.height+"px";s=n}};var%20u=function(n){document.body.style.cursor=e;if(n.target.parentNode)n.target.parentNode.removeChild(n.target);if(t.parentNode)t.parentNode.removeChild(t);window.removeEventListener("click",u,false);window.removeEventListener("mouseover",o,false);n.stopPropagation();n.preventDefault()};window.addEventListener("mouseover",o,false);window.addEventListener("click",u,false)})();void(0)
