Night Mode Pro is a Firefox extension that optimizes screen brightness based on the time of day. It features two distinct modes: Day and Night. In Night Mode, the extension dims the screen, providing a dark background with adjusted text colors for improved visibility in low-light settings. Conversely, Day Mode returns the display to its standard brightness, facilitating a comfortable viewing experience during daylight hours.

Beyond its basic functionality, Night Mode Pro offers users the ability to customize brightness levels for enhanced comfort while browsing. It also includes a whitelist feature that allows users to manage exceptions for specific websites, ensuring compatibility and a smooth experience across different online platforms. This makes Night Mode Pro an essential tool for users who regularly navigate the web in varying lighting conditions.
