Hello,
To restore animated thumbnail previews on YouTube, you can try using a userscript with a userscript manager extension like Violentmonkey. Here’s a quick fix:
Install Violentmonkey: Add the Violentmonkey extension to your browser.
Install the Userscript: Use this userscript: Restore Animated Thumbnail Previews.
Enable the Script: Follow the instructions to enable the script in Violentmonkey.
This should restore the animated thumbnail previews for you.
Best regards,
