Remove youtube video radius / rounded border

Thank you, perfect. Now i have 3 extensions installed to counteract YTs bad ideas (this, bringing back the thumbs down counter and removing shorts)

It Just Works.

Very easy and works.

simple and it works, thank you

Youtube started doing round corners on videos for me today. What a hideous feature to cut off portion of video. I like round corners on control elements, but not on video! This extension saved my day!

this solves a pressing problem of our time

Excellent extension. Looking forward to the update since YouTube changed the layout.

has stopped working on the video player ever since the layout was changed again, it works for thumbnails but not for the video itself

Works great to customize the youtube page look. A suggestion is it should affect the playlist thumbnails too on the homepage, they still keep the rounded corners.

awesome fantastic work keep it up
