Recent update adding detaching player is the best thing that happend to humanity since electricity. Rest of the features deserve five stars as well. Now go and install this add-on.

Unthinkable to use Youtube without it!

Very good extension! Makes youtube way nicer for viewing on a regular basis!

This adds features that Youtube lacks such as forcing the default playback resolution or detaching the player so you can see the video while reading the comments. Thank you very much to the developer

Well written and very helpful. Easy to configure as well.

It's amazing, and I know the developer has put so much effort into it.
