objLinks = document.links;
alert(objLinks.length);
for(i=0;i<objLinks.length;i++){
alert(objLinks[i]);

objLinks[i].style.color="grey";
objLinks[i].removeAttribute('onClick');
if(taskList == true){
if (secondFrame == "tasklistframe") {

Before doing that though, you should try this with Firefox 16.0.1.[[Update Firefox to the latest version]]
