Keep Screen On

Prevent your display or whole device from sleeping with one click.

Keep Screen On is a minimalist extension that does one thing exceptionally well: it prevents your display—or your entire system—from dozing off at the worst possible moment. At its heart, Keep Screen On offers a three-state toggle that cycles each time you click the toolbar icon: Normal – Default behavior; no power lock. Display – Keeps the monitor awake but lets the CPU idle normally. System – Keeps both the display and CPU awake, ideal for long builds or overnight tasks. A concise badge—blank, D, or S—shows your current state at a glance. Who Will Benefit Most?
