That site won't let you copy and paste in any browser. They have disabled this functionality to keep people from taking their content.

There's a great Firefox add-on that gets around this called RightToClick. You can install it here: https://addons.mozilla.org/en-us/firefox/addon/righttoclick/

Edit: I just tried using RightToClick to select and copy text on this page. It worked great!

Is the dom.event.clipboardevents.enabled pref set to true (i.e. default) on the about:config page?

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

To Mark Schmidt, This add-on worked perfectly. Thanks a lot I was able to copy, paste and print for study purpose. Thank you. To cor-el, by default dom.event.clipboardevents.enabled pref was set to true. and I changed to false by double clicking on it, but it did make no changes. It was indeed supposed to work but it didn't, and don't know why.

Note that you can use a bookmarklet like this in a lot of cased to disble the blocking.

javascript:void(document.onmousedown=null);void(document.onmouseup=null);void(document.onclick=null);void(document.oncontextmenu=null);void(document.onselectstart=null);

function disableText(e){return false;}
function reEnable(){return true;}
//For browser IE4+
document.onselectstart = new Function ("return false");
 //For browser NS6
if (window.sidebar){document.onmousedown = disableText;document.onclick = reEnable;}
window.onkeydown = function(e){if(e.ctrlKey == true){return false;}};

Cor-el, By any chance how can I embedded this boormarklet you mentioned to my Firefox browser. I kinda need a step by step, since I'm not really familiar with this approach. But it is a really good information. Thanks
