Thumbora — YouTube Thumbnail Viewer

Thumbora — YouTube Thumbnail Viewer is a simple, privacy-friendly Chrome extension that lets you preview or copy any YouTube video’s thumbnail directly from your right-click menu. Perfect for creators, designers, and marketers who need fast access to clean, high-quality thumbnails.

Key Features:

• View Thumbnail – Instantly preview the video’s thumbnail in a clean, centered pop-up. • Copy Thumbnail URL – Copy the thumbnail link for use in social posts, blogs, or design tools. • Open in New Tab – Quickly open the thumbnail in its full-resolution version. • Max Resolution – Automatically loads the highest available quality (maxresdefault.jpg). • Lightweight & Secure – No downloads, tracking, analytics, or remote code execution. • Works Everywhere – Home feed, Search results, Channel pages, Playlists, and Shorts.
