If all you need is a night mode, it is easy to achieve.
First, enable the option "Use custom background color for web pages" and fill the color value with "000000"(without quotes).
Second, create a file named night_mode.css and write the following content:
*:not(button):not(select) {
background-color:black !important;
color:white !important;
}
Save it and select it in the "Custom stylesheet" section.(enable "Load custom stylesheet" first).
These two steps will give you a perfect night mode, may be better than "Hight Contrast" extension.
