【问题讨论】：
您能否发布一个实时版本的链接，或者至少包含相关的 HTML 和 CSS？另外，您在哪个版本的 Firefox 中进行测试？ 嗨，克里斯，我已经包含了主要的 html 和 css，我无法发布链接，因为该站点是本地站点。我使用的是 firefox 7.0.1，Cheers，Danny。 伙计，当我要求 HTML 和 CSS 时，你肯定给了我很多！我无法显示相同的问题，但看起来页面的样式在我端没有正确设置。我要尝试的第一件事是从footer CSS 选择器中删除box-shadow（以及-webkit-box-shadow 和-moz-box-shadow）属性。如果这不起作用，了解您发布的 CSS 是网站的全部内容还是其中的一部分可能会有所帮助。
克里斯就在我前面！ :-) 如果没有实时站点，没有 ff7，排除故障有点困难，但我猜你的页眉和页脚阴影东西：-moz-box-shadow: 0px 0px 10px 0px rgba(0, 0, 0, 1 );因为它只在一侧。很明显，我们看不到一大堆图像。
对不起，伙计们！主要是堆叠出来..我认为这是一个错误，因为 wordpress 的前端管理栏有同样的问题..我两天前在为客户设置 wp 安装时注意到它..我很想发布一个链接，但我试图让这个小 jem 靠近胸部，希望它能让一些人的生活更轻松。这是我第一个在没有任何 php 知识的情况下启动的 php/jq 应用程序。我正在努力学习！！ :) 感谢你们抽出宝贵的时间，我想我将使用 jQuery Waypoints 来解决它。保重，丹尼。
【参考方案1】：
我在一个带有 PNG 背景和边框的 span 周围发现了奇怪的边框伪影。
我通过在父级上添加白色边框来“修复”该问题。它可能仍然有那些文物，只是它不再可见。
【讨论】：
【参考方案2】：这是一个 Firefox 错误，当您使用 position:fixed 和 background-color:rgba() 时，会导致该问题。您可以修复它，将position 更改为其他值，将background-color 更改为纯色或添加-moz-border-radius:0 1px。
【讨论】：
是的 -moz-border-radius:0 1px;边框半径：0 1px 0 1px；行得通。谢谢 @Bodman 我不建议使用通用边框半径来“修复”这个问题，因为这会影响所有其他标准浏览器，如 Chrome、Opera，而该问题仅在 Firefox 中出现。以上是关于Firefox 7.0.1 中固定位置元素的奇怪边框的主要内容，如果未能解决你的问题，请参考以下文章
