This add-on is particularly useful for users who need their computer to stay awake for extended periods of time, especially when using kiosk web apps.

With Strong Caffeine installed, users can ensure that their computer remains active and accessible without any interruptions caused by the sleep mode or screen saver.

One important thing to note is that Strong Caffeine does not provide an option to disable its functionality. Once installed, it will automatically prevent the sleep mode and screen saver from activating. Therefore, users should only install this add-on if they have a specific need for constant computer activity.
