Browser Border Theme

Make your browser come alive with dynamic colored borders that pulse and react to the music you're playing. 🎵 Audio Reactive Borders respond to any audio or video playing in your browser — YouTube, Spotify, Bilibili, Netflix, anything. The border color, intensity, and glow change in real time based on bass, mid, treble, and overall energy.
