W3C Validator Error with Animation Prefix

So I am building my own website and I wanted to make sure that there are no errors in my code. I have a simple animation that makes an image of an eye bounce. The animation works fine with chrome and safari. I've tested it on firefox and the animation doesn't work. The w3c css validator also states that the prefix I provided is not valid, "Sorry, the at-rule @-webkit-keyframes is not implemented"

The code I have is here: 

CSS

#eye:hover {
    -webkit-animation: bounce .75s ease-in-out;
}

@-webkit-keyframes bounce {
    0% {-webkit-transform: translateY(0);}
    35% {-webkit-transform: translateY(-40px);}
    50% {-webkit-transform: translateY(0);}
    70% {-webkit-transform: translateY(-25px);}
    80% {-webkit-transform: translateY(0);}
    90% {-webkit-transform: translateY(-5px);}
    100% {-webkit-transform: translateY(0);}
}

Any ideas would be greatly appreciated.

According to caniuse.com there is a known bug with Firefox and @keyframes. That may be the issue.

Hi Ken,

is this what you are referring to?:

"@keyframes not supported in an inline or scoped stylesheet in Firefox (bug 830056)"
