一切都很好而且非常快。

http://i.imgur.com/aoAPJhV.png
以下是HTML代码的另一张图片：http://i.imgur.com/PVA7wXY.png
向您展示svg图片。如您所见，代码有效。
所以是怎么回事？为什么Firefox有这么多问题？ HTML代码中是否有错误？我已经验证了它，但没有找到任何东西。

我还能尝试做些什么。通过background-image加载svg？但我真的想知道在Chrome中运行的原因，而不是在Firefox中。
特别欢迎任何帮助，特别是SVG加载问题。谢谢。

http://commons.wikimedia.org/wiki/File%3ATux.svg不是SVG图片。这是一个html页面，其中包含一个PNG图像，显示SVG图像在显示时的外观。
您正在寻找的SVG图片是http://upload.wikimedia.org/wikipedia/commons/3/35/Tux.svg，可以通过点击上面的维基百科页面找到它。
修复，让我在我认为是你想要的节点上的企鹅。我想其他图像也有同样的问题。
您的实际图片很大，因此您只会看到左上角是空白的。向SVG图像文件添加viewBox可能是您需要尝试获取viewBox的正确值所需的。

如果没有看到完整的代码，这只是猜测：
SVG Image with <image> tags does not show up in Firefox 16 when referred through GWT application
基本上，firefox不喜欢使用xlink：href元素，其中为另一个资源发出新请求。可能值得调查。
