To restore animated thumbnail previews, requires inline previews to be disabled in your YouTube settings. Note: not Greasemonkey compatible. v2.0 adds fallback option of a still image carousel for the homepage where YouTube has changed their data structure to no longer provide an_webp animated thumbnail urls, which is affecting some users; for such users non-homepage pages are unaffected and continue to use the an_webp animated thumbs.

I see you are correct about the sidebar stopped working. It looks like some Youtube website changes have caused it. If one turns on video previews in the user settings then the animated thumbnails come back for the sidebar but then you also have the inline video style previews on the homepage which we want to avoid. I should be able to get a fix working for this but probably not until next week.
Thanks for the update. In the meanwhile, the subscriptions and home pages have also stopped animating, with video previews disabled now it doesn't work anywhere, and with video previews enabled it works on the sidebar, but on the subscriptions and home pages it's the inline video previews.
Seems to be broken again.
The home and subscriptions pages work fine, but the sidebar recommendations next to videos don't animate anymore.
