Keep Screen On

About

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.
