Why won't my CSS work with Firefox?

more options

I am trying to use content: url to replace the content of my navbar with images. It works with Safari and Chrome, but not Firefox.

Here is an example of my css/html:

.menu-2222 a{
content: url("IMG LOCATION") no-repeat !important;
height:23px;
}

<li class="menu-2222"><a href="/Destination site" title="">title</a></li>


What am I doing wrong here?

It is probably the no-repeat !important part. The content text should only have the content and CSS rules need to be added separately.


a:before {
content: url(https://support.mozilla.com/media/img/favicon.ico);
font: x-small Arial,freeSans,sans-serif;
color: gray;
}

Still isn't working

I do not see pseudo-elements in the example. If I read the documentation it looks like in Firefox it only works with the pseudo-elements.

I have tried adding the :before and :after psuedo elements but still it still wont work. When I inspect in firebug my content: url line of css is not even there.
