Edit: Thank you to the developer for fixing it! Sorry it took me 5 days to see the update and edit my review. This addon is amazing, and I honestly can't see myself not using it, I've been using it for years, it has so many options and features to customize, you have to try it.

[Original Review: "It's currently broken, the cinema mode makes the entire screen black, including the video itself, so it can't be used at all. This is such a good extension so it sucks. I'll give it 5 stars once it's fixed."]
