Auto-Quality Preference (QPref) Description: Automatically selects video playback quality based on configuration (e.g., prioritizes 480p to save data) for players that support selection (HTML5 / hls.js). Features: Whitelists domains, overrides when on Wi-Fi. Simplicity: Detects DOM quality selector or intercepts player API (if available). Permissions: Content scripts, storage, optional network (less necessary if only DOM manipulation).
