I have been looking for such an extension for a long time. Finally found a good one.

BUG : since recently it beaks YouTube embeds on other sites: when clicking play it loads infinitely without playing

Es una exención simple y efectiva, la recomiendo

It works as it is supposed. It has so many options to make Youtube look and work as you want to.

Awesome extension! It really helps on not getting distracted.

The amount of distractions removed really helps me and my inattentive ADHD. Thank you so much for making the modern world a more accessible, straight forward and friendly place to be! :D

Exactly what I wanted.

Whoever created this is an angel and is helping me to stay more calm.
