About Tab Sleep – Auto Suspend Idle Tabs

Tab Sleep automatically puts your idle browser tabs to sleep freeing up RAM without closing them or losing your work. If you're the type who keeps 20, 30, or 50+ tabs open at once, you already know the problem: Chrome slows down, your fan spins up, and your laptop struggles to keep up.
