You don't need the -moz prefix in Firefox 23+, you can just use the intended CSS keyframe declaration (which you don't have in your current CSS). This will work in IE10+ as well. You also don't need to wrap the animation name in quotes, either:

@keyframes blinkmoz
{
    0% {
        opacity:0;
    }
    25% {
        opacity:1;
    }
    75% {
        opacity:1;
    }
    100% {
        opacity:0;
    }
}

.fadein {
    animation-name: blinkmoz;
    animation-duration: 8s;
    animation-direction: normal;
    animation-timing-function: ease-in-out;
}
