I like it havent used firefox in years, but am Now.

This add-on is like black magic. Literally!

Before I was using Stylus, which has a different approach for dark theming. It usually gives a more polished result. The problem is that a theme has to be available for every page. And there are no themes for all pages, only for common ones.

Dark Reader instead works on all pages. And in most cases it looks like the page author designed the black theme generated by Dark Reader. Just perfect!
