Some YouTube videos are blocked for viewing outside particular countries or territories. However, because of the way that YouTube detect your location, it is possible to bypass the country checks by using an anonymous proxy server. ProxyTube extension for Google Chrome allows you to watch restricted YouTube videos in any country.
With the Chrome extension ProxyTube, there are no more un-unavailable videos due to copyright issues in any country. You can watch almost all video on YouTube.
However, while testing, I found that it cannot remove restriction from all videos, but there is no problem with some videos, it automatically redirects the video to a new player.
