The script doesn't work. I fixed it though, and optimized it.
I replaced beginsWith with indexOf, as it's faster and much shorter. I used the pre-defined documents.links instead of the slower getElementsByTagName. I also made it run on-load because it needed to be or else it wouldn't run.

window.addEventListener('load', function(){
Array.forEach(document.links, function(el) {
if((omd=el.getAttribute('onmousedown')) && omd.indexOf('return rwt(this')==0) el.removeAttribute('onmousedown');
});
}, false);
