You can make your own night mode. Just open up the developer tools (F12) and add custom CSS into the Style Editor. For example:
Code:
.page-body {
background : #2A3132;
}
.post {
background : #90AFC5;
}
a {
color : #763626;
}
You can do this on any browser. You could also install Stylus or other similar extension to have your style loaded automatically when you open a new tab.
