Sometimes updates lag a bit behind YouTube's let's-change-this-for-no-reason nonsense, but that's hardly his fault. Otherwise does exactly what you'd expect from the descriptions.

if you use YouTube, you need this add-on.

I love opening a lot of Youtube tabs without worrying about the f****n autoplay. That and the pinned player makes me lov this extension.

Makes it easier to manage dozens of youtube tabs to prevent them from all autoplaying and is good for multitasking with the additional video size options.

The loop feature also makes it easier to listen to music continuously.

very good

Really great, lightweight add-on. This is THE add-on for YouTube.

GUI works well and it does its job. The theming is my favorite part.
