Keep Awake (Screen Only) από Anthony

Keep Awake (Screen Only) is a lite addon that helps you keep your computer's screen (monitor) from turning off without changing the power settings in your machine. The toolbar button serves as an ON|OFF switch.

Note: Keep Awake (Screen Only) only prevents the computer's screen from turning OFF, it does NOT control your machine from hibernation (sleep).

To work with this addon, simply turn the addon ON (with yellow toolbar icon) and your screen will NOT turn off at all. This add-on does not change the power settings in your PC/MAC. For example, even if you have set to turn the screen OFF after 5 minutes when this addon is active, your monitor will not be going to turn off at all.

To report bugs, please fill the bug report form in the addon's homepage.
