Settings and presets are stored only in your browser. PLEASE NOTE Copy-protected (DRM) streams don't release their audio and picture to extensions. There speed, picture filters, loop and frame stepping work, but audio effects, the picture delay and screenshots don't. The system audio analyzer can still show their spectrum.
