Doppelganger is an Adobe AIR, lightweight, drag and drop download manager for online videos. Unlike most video download extensions, Doppelganger allows you to download a video without visiting its page first. Anywhere there's a link to the video's page, simply drag the link to Doppelganger and the download will begin.
