Problems with different browsers

Hi Caroline,

I am absolutly new with worldpress, so I hope my question is not too stupid. I get the circles with picture not visible on firefox, only if I do mouse-over. On Safari and Chrome the site works well. I alrealy deleted my history and my cache (as halalmelo suggested one week ago), but it still doesn’t work… even on different systems (pc/mac). I just checked at opera, and there is the same problem as with firefox. And at internet eexplorer 8 the circels are squares.

What did I wrong? What can I do? The theme is so nice… I would love to use it properly ?? https://www.edina-medra.de
