Chosen solution

That image has an opacity specified that IE might not support:

img {-webkit-transition: opacity 0.55s linear; opacity: 0.65;} 
img:hover {-webkit-transition: opacity 0.85s linear; opacity: 0.95;}

There are also a lot of images on that page that are scaled up or down to 450px and Firefox doesn't (always) do a good job in scaling images (Bug 486918), so it is always best to avoid that to get the best results.

 img { opacity:1 !important; }

Thanks for responding! I guess I'll try to recreate the gif and fix the scaling issue.

You're welcome

That GIF image should be OK as I'm not seeing any issues with it on Linux and it isn't scaled (85x85).
Maybe only remove or override the CSS rule and set the opacity of that image to 1 as that isn't needed for that image.


.portrait { opacity: 1; }
