+## FAQ
+### Q: No action works on some video sites
+A: This extension only works [HTML5 video player](http://www.w3schools.com/html/html5_video.asp) (e.g. YouTube.com). It means this extension does not work on the video sites using Adobe Flash Player or other unique video player. Sorry about that.
