I recently discovered a nice Youtube extension that replaces all thumbnails with a screenshot from somewhere within the video. I feel it gives a better insight into the content of the video compared to the clickbait cover photo they everyone adds now. I still use YouTube far less than I used to in the past. It's probably a combination of less interesting content being made now and the increasingly egregious ads.
