Browser Extensions/Add-Ons: Look for extensions that are specifically designed to hide YouTube thumbnails. Extensions like Turn Off the Lights can dim the entire page, including thumbnails, giving you more control over what you see.
Custom Ad Blocker Filters: If you’re using an ad blocker like uBlock Origin, you can create custom filters to block elements, including thumbnails, on YouTube pages.
YouTube Settings and Features: While YouTube doesn’t offer a direct “hide thumbnails” feature, using YouTube in Restricted Mode can limit the visibility of certain types of content, which might indirectly affect thumbnails visibility.
Custom Scripts: Tech-savvy users sometimes write their own custom scripts to modify web page elements, including hiding thumbnails.
That’s right about it.
Hiding Thumbnails on Mobile Devices
Unfortunately, you can’t disable/hide thumbnails for phones and tablets.
As of today, disabling thumbnails works just for computers.
