Firefox Plugin正在下载

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，但这似乎颇具挑战性。我知道它做了一些事情，但是在图像，flv和mp3等内容中，内容似乎放置在文件中，但是当我尝试查看它们时，它们不是可查看/无效的格式。

我想我只需要做一些MimeType或文件格式的东西。它确实看起来不错，但显然缺少一些东西。

在此先感谢！

好了，好，我不能figre说出来，所以我所做的就是有一个C＃程序做文件系统观察（谷歌它），当它看到文件大小界限我一直在寻找，它内部的文件复制并重新命名为我需要的地方。这不是一个FireBug插件，但它确实有效。
