Is ChromaTube - YouTube Progress Bar Customizer safe?

Low risk

ChromaTube posts its extension runtime ID into YouTube pages when its content script starts.

On YouTube pages, ChromaTube runs at document start and sends a window message that includes a type built from the extension's runtime ID and the content script name. Page scripts on YouTube can observe that message, but the recorded claim does not show browsing data or page content being sent to a remote server.
