Keep Screen On
Extension Actions
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.
