Problem with Foat in Safari Mac and Mozilla PC

I'm floating images in my css with this css:

div.floatright
{
float: right;
width: 102px;
margin: 0px 0px 10px 10px;
background-color: #f1f1f1;
padding: 10px;
border: 1px solid #666;
}

And adding it to my page with this code:

<div class="floatright">
			<img src="images/hance.jpg" alt="" width="200" height="200">
			<strong>Whooa!</strong>
			<div style="clear:both"></div>

		</div>

The problem is that in IE6 on PC it formats the picture fine, but in Sarfari(mac) or Mozzila(pc) it pushes the pic into my subnav div on the right. It should push it left into the text.

Also in IE 5.5(mac) all of my subnav div on the right pushes down under my mainpage content div. Any suggestions would be great!!
