Justin Nunya (ID: 00000073555534ec) Voted 5 ★ - Updated 08/22/2021 I love this extension but it re-arrnges my YouTube player buttons to the right side for some reason, and my search button at the top of my YouTube page is smaller than it should be, other than that I love this extension. Oh would be sick if you could view descriptions from the recommended video sidebar too!! And when you search for vids
