X.com Heavy JS Optimizer+ is a high-performance userscript that dramatically reduces lag, scroll jank, and CPU load on X.com (Twitter).
It intelligently removes redundant animations, limits repainting, pauses offscreen videos, and caps JavaScript frame rates β all without breaking the core site experience.
π§Ή Lightweight CSS Cleanup
Removes heavy effects (backdrop-filter, blur, gradients) and disables GPU-stressing layers.
βοΈ Passive Event Optimization
Forces passive: true on scroll/touch listeners for smoother rendering.
ποΈ Smart Video Control
β’ Only one video can play at a time
β’ Auto-pause when scrolled offscreen
β’ Prevents auto-play and decoding spam
𧩠DOM Feed Garbage Collector
Keeps only the last N tweets in the DOM to prevent memory bloat.
(Configurable from userscript menu.)
π Metrics Blocking (Optional)
Blocks unnecessary telemetry calls like scribe, engagement, and client_event.
β‘ Aggressive Runtime Mode
Auto-detects long tasks and dynamically limits FPS (requestAnimationFrame) to maintain stability.
π€ Tab Visibility Safety
Auto-pauses all videos when tab is hidden.
