About Henry: Tab Manager — Pause Background Videos & Save Energy
Henry watches your tabs so you don't have to.
Every time you leave a tab with a video playing in the background, Henry catches it instantly and asks if you want to pause it. Every time a tab sits idle for too long, Henry flags it for sleeping. The result: less wasted energy, less RAM consumed, and a browser that actually respects your machine.
What Henry does:
Detects background videos the moment you switch away and offers to pause them immediately
Flags idle tabs and lets you sleep or close them in one click
Auto-pauses videos and auto-sleeps tabs when you've been away (optional)
Saves energy in a way Chrome's built-in Memory Saver never does, Chrome doesn't touch videos, Henry catches them every time
Why it matters:
Background tabs running videos or heavy JS consume real electricity. Henry frees that energy the moment you stop watching, not when Chrome decides RAM is low. All savings stay local: no data ever leaves your device.
Earn points as you save:
Henry gamifies your impact with a points system, daily streaks, and 8 unlockable animal companions: from Henry the domestic cat at level 1 to Gold Henry at the top. The more energy you save, the further you progress.
Henry respects your privacy:
No data collection. No analytics. No servers. Your points, your stats, your settings, all live on your device via Chrome's local storage. Henry has no backend.
Tips:
📌 Pin Henry to your toolbar so you see the badge count whenever tabs need attention.
The badge turns red when Henry's auto-sleep feature kicks in — that's your signal to check back in.
