Is BetterPlayer - A Modern Video Player safe?

Replaces Chrome’s default video player with keyboard controls for playback, volume, captions, fullscreen, and seeking.

This extension provides a modern video player experience in Chrome with shortcuts for common playback actions. Users can play or pause, skip forward or backward by set intervals, move frame by frame, toggle captions, reload, enter fullscreen, adjust volume, mute, and jump to the start, end, or a percentage of the video.
