Custom Dark Mode is an easy-to-use browser add-on that can customize your dark mode. It is a simple tool that allows you to create your own dark style for the web. The interface is a standard browser toolbar and it can be opened with just a single click. Once you open it, you can set various settings for various elements and even modify the opacity for all HTML elements. By the way, there is no need to create any profiles or anything like that. All the settings are saved automatically to the memory and you can use them offline.

Custom Dark Mode can be turned ON/OFF or modified with a single click. You can also use a big torch button at the top center to turn the add-on ON/OFF.
