YoukuOpener allows you to open the embed video in Youku website. By opening the video in Youku website you can : Download, Add to…
Some embed videos do allow you to open them in Youku.com website, but some don't. That is the problem YoukuOpener to solve.
If there is a Youku video embed in the page, by clicking the YoukuOpener button(icon in the toolbar) it'll open that video in Youku website for you. If page embeds multi Youku videos, it'll show you a menu with each url/title. You can simply click one of them and that will be opened in a new tab.
YoukuOpener可以把内嵌的优酷视频在优酷官网上打开(有些网站并不支持该功能), 在优酷官网打开的好处是可以下载视频, 收藏, 分享, 转发，查看评论以及加速视频的加载速度。
