Thanks for this nice theme :)
i have a problem with images inside a grid not scaling (at all) in firefox. they do scale fine in chrome however.
my link:
http://www.tsv-hohenbrunn-riemerling.de/
if you resize the page with firefox the green circle icons on the main page do not scale and the 2 right icons can disappear with certain browser window sizes.
on chrome it works really nice and smooth.
