TabHibernate by R Nichols

TabHibernate keeps your browser fast by putting idle tabs to sleep. Suspended tabs are unloaded from memory but stay in your tab bar, ready to reload the moment you click them.

😴 Auto-suspends tabs after a configurable idle period (1–120 minutes)
🔋 Dramatically reduces RAM and CPU usage with many tabs open
✅ Whitelist — protect specific sites from ever being suspended
⚡ Hibernate All and Wake All buttons for instant manual control
📊 Live tab overview showing Active, Idle, and Sleeping status for your current window
💾 All settings stored locally — no accounts or sync required

Ideal for power users, researchers, and anyone who keeps dozens of tabs open at once.
