Do you access you tube videos regularly..? Then this Google chrome plugin (extension) Youtube link box is for you only.
One small box will be added just beside of Address bar after you install Youtube link box. Simply click on the box, one text box will be appeared (see first figure) and then type videos which you want to watch. Related videos list will be displayed as shown in the following figure.
You can still navigate using < , > symbols, play, create playlist here. As soon as you click on the video youtube video played in the next new tab.
Once you select on one video other videos are disppearing from the list. Again we have to come from the scratch to display the list again. I think this is little limitation in this. However you can see related videos in youtube itself.
Don’t forget to download youtube videos after you enjoyed it. Good luck.
