Is Bookmarker for YouTube™ safe?

Medium risk

Bookmarker for YouTube loads saved video thumbnails over cleartext HTTP from YouTube's image server.

When you open the popup, the extension displays each saved bookmark with a thumbnail loaded from img.youtube.com over HTTP. Those requests include the saved YouTube video IDs in the URL, so the bookmarked videos are exposed to the network path for each thumbnail request.
