firefox不支持text-overflow一直让人很折腾。。不过还好有大虾为我们提供解决方案。。text-overflow: ellipsis for firefox

Firefox still does not implement the proposed CSS3 text-overflow property. It does however provide a similar behaviour for the XUL description element. Furthermore, it does support XBL bindings through CSS. This leads to the following solution:

.ellipsis { text-overflow: ellipsis; -moz-binding: url('ellipsis.xml#ellipsis');

<?xml version="1.0"?> <bindings xmlns="http://www.mozilla.org/xbl" xmlns:xbl="http://www.mozilla.org/xbl" xmlns:xul="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" > <binding id="ellipsis"> <content> <xul:description crop="end" xbl:inherits="value=xbl:text"><children/></xul:description> </content> </binding> </bindings> 

xul:description
的crop原来是那样强。。除了可以点点点掉后面的。。还可以点点点前面或者中间部分的。。这个功能可是非常实用哦，不知道W3C虾米时候也给这样的CSS属性让我们简单搞定一大堆问题呢。
