FireFox 3.6 Default Style Border Issue

I want to override a FireFox 3.5.6 style sheet which is placing a border around one of my images within a anchor ? Without placing a reset rule that could mess up the entire layout ?
Why brake what isn’t broken.

|:-moz-any-link img, img[usemap], object[usemap] {
border: 2px solid;

a img {
    border: none;

That’ll do it. If only some/certain links are to be targeted, add selector specificity.
