Question

我正在尝试创建一个SIMPLE插件，不需要任何界面，它将自动下载并保存到“Desktop / MyFolder /”页面加载的所有内容。我的想法是扩展FireBug，但这似乎相当具有挑战性。我做了一些事情，但是在图像，flv和mp3等内容中，内容似乎放在文件中，但是当我尝试查看它们时，它们不是可查看/无效的格式。

我在想我只需要做某种MimeType或文件格式的事情。它看起来确实很好，但显然缺少一些东西。

提前致谢！

好吧，我无法想象，所以我所做的就是有一个C＃程序做一个FileSystem Watch（谷歌它），当它看到我正在寻找的文件大小范围内的文件时，它复制并重命名它到我需要的地方。它不是FireBug插件，但确实有用。
