Instant video previews in popup player by hovering or clicking video thumbs. Video ratings and resolution data shown on the thumbs. Gets video information without using a YouTube API key, which can be banned or limited.
Works perfectly for me on Firefox 74 on Ubuntu on 28 March 2020
Ratings and Previews work fine. I don't know how you did it without an API key but it does work. (The ratings-bar addon on the official Firefox addons site is the only other ratings addon that works — and that needs you to get a Youtube API key before it works properly.)
I didn't want the video preview feature but it worked fine before I switched it off in the options.
