title: firefox is adding space after footer tag
body: <p>This is not happening in chrome or ie. Firefox instead is adding 50px after my footer. with analyze element and firebug it is showing that that space is outside html tags. here is the link: <a href="http://www.sociallab.ro/index_romana" rel="nofollow">http://www.sociallab.ro/index_romana</a>
