Control your browser's global screen brightness to use sites that do not support the native dark theme

Image from store Adjust Screen Brightness
Description from store This extension reduces the screen brightness level for both daytime and nighttime periods based on user-defined values. It is meant to be used with websites that do not support the native dark theme. It is designed to reduce eyestrain while reading documents online when dark mode is not supported. To enhance usability the extension offers two different values for daytime and nighttime duration. Notes: 1. By setting the brightness level to 100%, the extension has no effect on browser tabs (does not inject any CSS styling) 2. It is recommended to configure the start time for both daytime and nighttime. By default, daytime starts at 08:00, and nighttime starts at 19:00. Features: 1. You can now increase or decrease the brightness level from the popup interface or by configuring custom keyboard shortcuts 2. You can add or remove a website from the popup interface. By removing it, the extension does not alter the website brightness at all. This way, you can turn off the extension on websites that support dark mode. 3. This extension does not reduce the screen brightness when printing a webpage. There is a CSS selector that only affects "screen" type displays.

  • (2019-12-09) Martin Ved-Viete-Kto: 1/ I removed it from Chrome, but the brightness stayed low (the browser tab is still dimmed at the time it was set in the extension). 2/ I reinstalled it, but it didnt fix the problem, it looks like the new value is multiplying the old value. At 100% new value the screen is still dimmed at 80% old value.
