Show YouTube Thumbnails

A small extension to quickly fetch the thumbnails of YouTube videos.

When on a YouTube video page, a button will be shown in the browsers address bar. You can view the video's thumbnails by clicking the button.

Acknowledgments

Thanks to this Stack Overflow answer for providing the thumbnail URLs. I've re-searched this answer time and time again until finally codifying the logic into this extension.

Thanks to Font Awesome by Dave Gandy for the extension icon.
