在Firefox中破坏的页脚

Question

我遇到一个奇怪的问题，我的简单页脚在Firefox中无法正常显示。它基本上是一个显示内联导航向左浮动，一个标签向右浮动。似乎在其他所有浏览器中都能正常工作。这是代码：

HTML

<div id="footer_wrap">
<div id="footer_area">

<ul id="footer_nav">

    <li><a href="{site_url}" {if segment_1 == "" OR segment_1 == "view"}class="active"{/if}>Blog</a></li>
    <li><a href="{path="/archives"}" {if segment_1 == "archives"}class="active"{/if}>Archives</a></li>
    <li><a href="{path="about"}" {if segment_1 == "about"}class="active"{/if}>About</a></li>

</ul>


    <a href="{site_url}" id="footer_logo">&copy; {current_time format="%Y"} {site_name}</a>

<div class="clear"></div>

</div> <!-- end footer area -->
</div> <!-- end footer wrap -->

CSS

#footer_nav {float: left; list-style: none;}
#footer_nav li {display: inline; margin-right: 20px;}
#footer_nav li a {
    font-weight: bold; 
    color: #FFFFFF; 
    opacity: 0.8;
    filter: alpha(opacity=80);
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=80)";
    text-transform: uppercase; 
    font-size: 12px;
}
#footer_nav li a:hover {
    font-weight: bold; 
    opacity: 1;
    filter: alpha(opacity=100);
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=100)";
}
#footer_nav li a.active {
    font-weight: bold; 
    opacity: 1;
    filter: alpha(opacity=100);
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=100)";
}

#footer_logo {
    float: right; 
    color: #FFFFFF; 
    font-size: 18px; 
    opacity: 0.8;
    filter: alpha(opacity=80);
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=80)";
    -webkit-transition: all 0.1s ease-in-out;
    -moz-transition: all 0.1s ease-in-out;
    -o-transition: all 0.1s ease-in-out;
}
#footer_logo:hover {
    opacity: 1;
    filter: alpha(opacity=100);
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(opacity=100)";
}

以下是简化代码，只有两个验证错误是针对图像上的空“高度”值

<div id="footer_wrap">
<div id="footer_area">

<ul id="footer_nav">

    <li><a href="#">Blog</a></li>
    <li><a href="#">Archives</a></li>
    <li><a href="#">About</a></li>

</ul>


    <a href="#" id="footer_logo">&copy; 2011 Mysitename</a>

<div class="clear"></div>

</div> <!-- end footer area -->
</div> <!-- end footer wrap -->

最后想出来的人，这是一个流氓括号，而不是我的CSS样式表中更高的大括号，这意味着下面的所有内容都没有被firefox或opera看到
