Hello world应用程序无法在Firefox 7.0.1中工作

Question

我无法在Firefox 7.0.1中打开Hello world应用程序。我正在开发使用this教程从煎茶documentation.When我打开Firefox网页开发者控制台这个程序，我发现下面的CSS错误：

我想知道为什么这么多的错误来了，如何解决这些错误？

我只是在相同版本的Firefox（和版本8.01）中做了同样的事情，并且我得到了和你一样的警告（不是错误）。

显然，这是一个老问题：现在 http://www.sencha.com/forum/showthread.php?10956-Solved-css-warnings-feedviewer-in-firefox-2
