Question

How can I set a specific margin for Firefox in CSS? I tried -moz-margin:0px;

My problem is in every browser, even IE works,

but firefox fails at my CSS now… There are certain links that move like 1px to the left when I rollover them…

Your problem probably lies elsewhere, but here’s how you target Firefox only:

@-moz-document url-prefix() {
    a {
        margin: 0;
    }
}
