Is Thumbnail Downloader safe?
Thumbnail Downloader sends the current YouTube or Vimeo video ID to youtube-thumbnail-grabber.com for downloads.
When you use the thumbnail download button on a YouTube or Vimeo page, the extension opens youtube-thumbnail-grabber.com with the current video identifier in the URL. This is part of the expected download flow and sends that video-page identifier to the service that provides the thumbnail download.
