Current version: 0.0.2
This is a simple Chrome extension for playing all of the embedded Youtube videos on a single web page back-to-back. It creates a toolbar button that toggles a panel in which the videos play. Currently it only works on pages whose videos are all in <iframe> tags and share a common HTML class, but it can be adapted easily by changing the findVideos method (and any Pull Requests that improve on that function are very welcome). Enjoy!
The easiest way to install the extension is via the Chrome Web Store (free)
