I'm using the following code: CSS
#buttonbar {
   background-image: url(art/buttonbarbg.jpg);
   background-repeat: repeat-x;
   background-position: top left;
   border: 1px solid #000000;
   width: 100%;
   height: 60px;
   float: left;
   overflow: hidden;
   <div id='buttonbar'>&nbsp;</div>

For some reason, when viewed in FF this extends 2px past the edge of the normally viewable area, whereas in IE it displays as intended.

Firefox follows the CSS spec and extends borders 1 pixel beyond the box size. IE, however, does not do this. IE adds a 1 pixel border inclusive of the box size.

Add the correct doctype to force IE to standards mode.

Actually, if you're going for 100% width -- do nothing. Divs are always the full width of the container that they're in (i.e. width: auto).
