Height difference between Safari and FF

Hey Guys

I have set a px height for one of my div tags and it displays a huge difference between FF and Safari. Safari is atleast afew 100px longer. See code below:

HTML

[code=html]<div id=”ContactList”>
<div id=”contactListSearch”>
Search
</div>

<div id=”Contacts”>contacts here
</div>
</div>[/code]

CSS

[code=html]#ContactList {
height : 100%;
position : relative;
float :left;
margin-top : 2px;
padding-bottom : 8px;
border : solid 1px #dddddd;
background-color : #efeeee;
width : 150px;
}
#contactListSearch {
padding-top : 15px;
margin-left : 9px;
font-size : 70%;
line-height : 1.6em;
}
#Contacts {
margin : 10px 0 0 8px;
width : 130px;
height : 772px;
background-color : #FFF;
border : solid 1px #CCC;
overflow : auto;
}[/code]
