Clients icons

Is there anyway to make the client icons show constantly instead of only on mouseover?

Ignore this

When I’m looking at the theme in firefox, even with the demo the client icons aren’t showing until the mouseover. All I see is blank space. Anyone have any ideas? It’s showing fine in chrome.

Thanks for noticing.
Add this in your style.css please:

.clients li img {
       filter: grayscale(100%);
