提供简便的方法，在弹出窗口中打开 YouTube 播放器
This extension provides a simple way to open any YouTube video (including videos embedded in other sites/pages) in a "popout" window which you can freely position and resize.
When viewing any YouTube video, whether directly YouTube, or embedded on any other website, you can either:
- Right-click on the video and click the "Popout Player" option (at the bottom of the menu that is displayed)
- Click the new icon (a square with an arrow pointing out of the corner) in the lower right corner (by the settings and fullscreen icons)
