Βελτιώστε την απόδοση του X.com/Twitter: αφαιρεί βαριά CSS, περιορίζει τα FPS, μειώνει το μέγεθος του DOM, θέτει σε παύση βίντεο εκτός οθόνης, αποκλείει τα αναλυτικά στοιχεία και ενεργοποιεί αυτόματα την επιθετική λειτουργία όταν εντοπίζεται καθυστέρηση.

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 — all without breaking the core site experience.
🧹 Lightweight CSS Cleanup
Removes heavy effects (backdrop-filter, blur, gradients) and disables GPU-stressing layers.
⚙️ Passive Event Optimization
Forces passive: true on scroll/touch listeners for smoother rendering.
🎞️ Smart Video Control
• Only one video can play at a time
• Auto-pause when scrolled offscreen
• Prevents auto-play and decoding spam
🧩 DOM Feed Garbage Collector
Keeps only the last N tweets in the DOM to prevent memory bloat.
(Configurable from userscript menu.)
📊 Metrics Blocking (Optional)
Blocks unnecessary telemetry calls like scribe, engagement, and client_event.
⚡ Aggressive Runtime Mode
Auto-detects long tasks and dynamically limits FPS (requestAnimationFrame) to maintain stability.
💤 Tab Visibility Safety
Auto-pauses all videos when tab is hidden.
Available via ViolentMonkey / TamperMonkey menu:
