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.

  • v2.0 12/02/2025

    Add a fallback option for users affected by YouTube's recent code changes that they are no longer providing an_webp animated thumbnail URLs on the homepage. The fall back makes a still image carousel/slideshow of some available screenshots apply to the homepage. At time of writing only some users affected and only the homepage is affected, other pages continue to work with an_webp animated thumbnails.
