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. Tab Sleep fixes this by discarding tabs you haven't touched in a while, while keeping them right where they are in your tab bar just one click away from reloading exactly where you left off.
