Here is a neat trick, go to any web page and enter the following javascript in the address bar:

javascript:(function(){var x,d,i,v,st; x=open(); d=x.document; d.open(); function hE(s){s=s.replace(/&/g,%22&%22);s=s.replace(/>/g,%22>%22);s=s.replace(/td{vertical-align:top; white-space:pre; } table,td,th { border: 1px solid #ccc; } div.er { color:red }%22); for (i in window) { if (!(i in x) ) { v=window[i]; d.write(%22%22); } } d.write(%22

Variable	Type	Value as string
%22 + hE(i) + %22	%22 + hE(typeof(window[i])) + %22	%22); if (v===null) d.write(%22null%22); else if (v===undefined) d.write(%22undefined%22); else try{st=v.toString(); if (st.length)d.write(hE(v.toString())); else d.write(%22%C2%A0%22)}catch(er){d.write(%22 %22+hE(er.toString())+%22 %22)}; d.write(%22

%22); d.close(); })();

It will open a new window and display all the javascript variables loaded for that particular page.  NEAT!
