Internet Explorer and Gecko based browser do not render indents
for list the same way. You cam make them the same wih CSS.

First you need to remove/clear the left padding and margins.

ul{
margin-left:0;
padding-left:0;
}

Now, to indent the list XXpx just add the the number of pixels
to either the left padding or left margin.

ul{
margin-left:XXpx;
padding-left:0;
}
or
ul{
margin-left:0;
padding-left:XXpx;
}
