These days many websites are not allowing us to right click
 even if you keep security settings to low , it is not enabled
 To resolve this issue just create a book mark with
name : enable right click  and
URL as follows

javascript: function r(d)d.oncontextmenu=null;d.onselectstart=null;d.ondragstart=null;d.onkeydown=null;d.onmousedown=null; d.body.oncontextmenu=null;d.body.onselectstart=null;d.body.ondragstart=null;d.body.onkeydown=null; d.body.onmousedown=null;};function unify(w){r(w.document);if(w.frames.length>0){for(var i=0;i<w.frames.length;i++){try{unify(w.frames[i].window);}catch(e){}};};};unify(self);

then a popup comes up with yes or no , select yes and proceed So when ever you come across such page just click this icon and then try to select it will help you do that .................
