Is Twitch Fullscreen Plus safe?

This extension shows Twitch chat as a customizable overlay while you watch streams in fullscreen.

It lets you toggle fullscreen viewing with chat visible on Twitch streams, then drag, resize, and reposition the chat overlay. You can customize the chat appearance and hide selected Twitch elements such as leaderboards, community highlights, points, and hype trains.
