[Resolvido] Firefox adiciona espaço inexistente

Olá

Ao usar as tag h1, h2... h6, p o firefox separa as duas DIV(header e content) /applications/core/interface/imageproxy/imageproxy.php?img=http://img209.imageshack.us/img209/3776/espacote8.png&key=51cd25bd24052ed8bf314b4813f9ef6416585d8f056fa01f66148aa5125f782e" alt="Imagem Postada" />. Como posso resolver isso? Obrigado
