User Reviews

Honestly great and advertises exactly what it does. However, I believe I found a bug that could have occurred through one of YouTube's updates. It was working great up until a couple days ago. Thumbnails for suggested videos to the right of the video-player have reverted back to having their rounded corners. Although things like the homepage thumbnails, subscription thumbnails, and channel thumbnails all still appear with sharp edges. I have seen this bug happen on both PC and Mac for the Firefox browser. I have not seen a way of contacting the maker of this extension other than a link to his GitHub page. I don't want to have to make an account solely just for that.
