Remove advertisements from 4oD streaming
Channel4 now disables 4oD streaming content when ad-block is detected so that users must disable ad-blocking and watch advertisements if they want to watch streaming content.
Even with ad-block disabled this extension should block ads that would appear in 4oD streamed content.
Note: The extension doesn't block any other banner advertising or tracking content on 4oD.
Code for the extension is available on GitHub here https://github.com/zapthedingbat/4od-ad-block
