Dotted border has extra pixel in Firefox

When using a dotted border on only one edge of a DIV, Firefox always puts a dot at both ends of the line, even if the pattern would normally call for a space. I'm guessing it does this to make sure the border is the right width, but I'd like it to give the pattern higher priority.

Paste the code below into an HTML file and you'll see what I mean. IE7 renders the pattern right, but the line is only 99 pixels long, which is fine by me. Opera alters the number of spaces between the dots in a best-effort approach to get the pattern and size right. Firefox, though, will have two dots at the end of the line.

Anybody know how to get Firefox to leave off that last dot, short of making sure all my border lengths are an odd number of pixels (which I can't guarantee with dynamic content).
<html>
 
<head>
<style>
 
DIV.bottom {
   border-bottom: 1px dotted black;
   width: 100px;
}
 
DIV.right {
   border-right: 1px dotted black;
   width: 10px;
   height: 100px;
}
 
</style>
</head>
 
<body>
 
<div class="bottom"></div>
&nbsp;
<div class="right"></div>
 
</body>
 
</html>

I don't think there's any way of modifying how firefox renders the dots.  The only alternative solution that I can think of would be to create a 2x1 background image that has one black pixel and one white/transparent pixel and then tile the image to get a dotted line effect.

By the way, the dotted lines in IE6 and below actually turn out as a dashed line.  So, you may want to take that into consideration.

Yeah, I declared IE6 a lost cause ages ago. We've tried using the background image trick like you suggested, but we ran into issues when we wanted to have the dotted line as a separator and have a background color on the div itself. We worked around it by just adding more divs, but more elegance would be sweet.

You could give the div a background color and the image.  Maybe something like this...
div
{
    background: blue url(dottedline.gif) repeat-x left bottom;
    border: none;
    padding-bottom: 25px;
    margin-bottom: 25px;
}

Thanks for the info. I'll accept your first comment because, in this case, "you can't" seems to be the right answer.
