Is +Sub safe?

Low risk

+Sub lets the current webpage request video details and frame thumbnails after the user clicks the extension.

When the user clicks +Sub, it injects scripts into the active tab and its frames. The injected script accepts page messages marked as +Sub requests and can respond with video status, timing details, and a thumbnail image drawn from the video frame.
