Fantastic add-on, thanks for the hard work in fixing any issues that crop up!

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."]

Love this extension/add-on and have been using it for years. Just today, the "Automatically expand the video player" option broke and is not fully expanding to the bottom of the screen and cutting off the bottom of the video/stream. Once this is fixed Ill update to 5 stars

Edit:
Its been fixed! Thank you

FACIL DE USAR, SIN PROBLEMAS Y MUY ACCESIBLE EN SUS AJUSTES.

MUY ORIGINAL

I love this extension! It makes watching YouTube so much better. Best feature is being able to control the playback speed - sometimes even 2x isn't fast enough. I now get salty when I watch YouTube on my phone because there is nothing like this for mobile. Highly recommend!

I love this extension. Its got a couple big features that are so well done that I forget that they aren't just a default feature of youtube itself, like the mini-player that pops up when you scroll down to read the video description / comments.

One small feature that I wish it had, although I don't know if it would be possible, is to have each video you click open in a separate tab by default, instead of having to middle click than manually move over to the new tab.

High playback speed (x3) breaks when holding arrow keys to skip to unloaded part of the video. It downgrades to youtube's playback speed and the addon's speed just doesn't work untill reload of the page.
