No reaction of pictures once clicked on in Firefox

[matthieu-vergne]

When we comment the achievment of someone who has a picture for it, we should be able to click on the picture to see it fully. But it appears that it does not work on Firefox.

I suspect that is because there is not actual content in the link. The picture is set as background, but the link by itself (content between "a" tags) is empty. I suggest to put the picture inside the link (img component) rather than as a background, or put "something" inside which has the background picture. This way you actually click on the content of the link.
