Looks like the "Clickbait Remover for #YouTube" is available for #Firefox. Happy days.

"This extension replaces thumbnails with a frame from the video, effectively removing any clickbait while still showing a high quality thumbnail so you can still get a good idea of what the video is about. It can also modify titles to stop partial or all caps titles."
