Navigation and Firefox., works? Options

[Marlons]

I was just wondering, does this kind of navigation not work on Firefox anymore, because the links overlap and i can't get it to work.
Example

Or are my codes just outdated? if so anybody have any working codes?

For the links use the line-height code. Add it in the links and links hover code.

Example:

CODE

a.nav:link, a.nav:visited, a.nav:active {
font-family:century gothic;
text-decoration:none;
display: block;
color:black;
font-size:14px;
text-align:center;
background-color:transparent;
font-weight:normal;
line-height:25px;
width:193px;}

a.nav:hover {
font-family:century gothic;
text-decoration:none;
display: block;
color:white;
font-size:14px;
text-align:center;
background-color:640000;
font-weight:normal;
line-height:25px;
width:193px;}
