Firefox Plugin正在下載

Question

我正在嘗試創建一個SIMPLE插件，不需要任何界面，它將自動下載並保存到「Desktop/MyFolder /」頁面加載的所有內容。我的想法是擴展FireBug，但這似乎頗具挑戰性。我知道它做了一些事情，但是在圖像，flv和mp3等內容中，內容似乎放置在文件中，但是當我嘗試查看它們時，它們不是可查看/無效的格式。

我想我只需要做一些MimeType或文件格式的東西。它確實看起來不錯，但顯然缺少一些東西。

在此先感謝！

好了，好，我不能figre說出來，所以我所做的就是有一個C＃程序做文件系統觀察（谷歌它），當它看到文件大小界限我一直在尋找，它內部的文件複製並重新命名爲我需要的地方。這不是一個FireBug插件，但它確實有效。
