Facebook – Delete All Messages is a Google chrome extension that adds a ‘Delete All’  button in the messages page of your Facebook account.

The extension is immediately activated once you install it.  Simply reload your Facebook messages page and click on the extension icon in the menu bar in the upper right side. A panel of options and instructions will appear.
