  display: inline-block;

.MessageAvatar {
  width: 60px;
  height:60px;
  -moz-border-radius-topright: 10px;
  -moz-border-radius-topleft: 5px;
  -moz-border-radius-bottomright: 15px;
  /*-moz-border-radius-bottomleft: 20px;*/
  border-width: 2px;
  border-style: solid;

edit: as you can see.... bottomleft no corner... topleft 5px... topright 10px... bottomright 15px... all with a 2px border... for your orientation when planning the border-radius
