To use the Unblock Youku extension, you just need to download and install it on your Chrome browser, then you are done. A piece of cake, and easier than Mason and Change HTTP Request Header, right?

So, Unblock Youku is the best free tool for you to watch free online movies and TV series on Chinese video sites, when you are living outside Mainland China and fail to do that on Hulu, tvDuck, PrimeWire.ag or any other non-Chinese sites.
