Not yet adopted, but tested several times, this extension does exactly what it promises. The thumbnail are, most of the time, a smiling face spotted in the video. It's disconcerting, like any change in habits. But I think I'll get used to it quickly: YouTube seems less toxic!

Pas encore adoptée, mais plusieurs fois testée, cette extension fait exactement ce qu'elle promet. Les miniatures sont, la plupart du temps, un visage souriant, repéré dans la vidéo. C'est perturbant, comme tout changement d'habitude. Mais je crois que je m'y ferais vite : Youtube semble moins toxique !

I'm more of a fan of using the last frames instead of first frames, but now that Clickbait Remover is starting to fail more frequently (specially with shorts and recent videos), this is the best alternative for me. Nothing wrong with DeArrow, but I prefer the local approach. I would probably give 4 stars for the lack of customisation, but I'm giving 5 for visibility. Also, it's lightweight.
