This script disables YouTube's new rounded corners (reverts back to the previous layout from 2021.)

edit: btw i am using it on chrome with tampermonkey not firefox with greasemonkey in case you want to know
Thanks for this, it mostly gets rid of the stupid bubble text the buttons have on the video player. My only problem is that the like/dislike button doesn't work as it still has the roundness to it and is bugged I think, can you please look into it and maybe fix it in a update, thank you.
