Sundown Extension is a free add-on for the Chrome browser that offers a convenient way to toggle between day and night mode on web pages. With just a click, users can switch the entire page to a dark mode, making it easier on the eyes in dark or dimly lit environments. The extension also adjusts the text colors to ensure optimal visibility in night mode.

In addition to the day and night mode feature, Sundown Extension allows users to customize their Chrome browser's default new tab page. Users can choose from a selective gallery of abstract images powered by Unsplash to set as their background. The new tab page also includes a digital clock, displaying the current time in either 12-hour or 24-hour format based on user preference.

Another useful feature of Sundown Extension is the integration of Bing search. Users can conveniently search for information, images, videos, and more directly from their new tab page.

Please note that in order to whitelist a website from night mode, users can simply right-click on the webpage and select "Add site to whitelist."

Overall, Sundown Extension offers a simple and user-friendly solution for toggling day and night mode on web pages, along with additional customization options for the Chrome browser's new tab page.
