Is TimeTags for YouTube safe?

Clean risk

TimeTags for YouTube sends the current YouTube video ID to its API proxy endpoints when activated.

When you click the extension on a YouTube video page, it injects its interface and requests video details and comment threads for that video. Those requests include the current video ID and go to developer-operated API proxy endpoints used to load the extension's comments and chapters panels.
