Excellent for people like me that suffer from photosensitivity but perfect for everybody that is conscious about protecting the eyes while surfing. Many people don't know but constant exposure to the bright light of computer monitors, which is even more present in all the white colors online, is harmful for our eyes. Dark Reader is the perfect tool to reduce the eye strain while using your browser and I use it on Firefox, Chrome and the new Chromium-based Edge browser. Full of many useful options, fast and effective, Dark Reader is a must have add-on. Many thanks to all the devs that work on this.
