I have been using border-radius and box-shadow effects of moz and webkit.
//For rounded corners
-moz-border-radius:4px;
-webkit-border-radius:4px;
//For shadow effect
-moz-box-shadow:2px 2px 5px #000;
-webkit-box-shadow:2px 2px 5px #000;
Anyother unknown css effects of moz and webkit.
EDIT:
I have got some more css properties here
