Super

It saved my eyes.

Works brilliantly. Easy to use.

Makes a few sites unreadable, and some have ugly colour schemes, but I can't really blame them. Besides, you can just turn it off in that case.

Great extension. Flips colors naturally while keeping all items as visible as they are in the site's original (non-dark) layout. Very simple to use and highly customizable: You can easily fine tune the darkness intensity. For instance, if you prefer a dark grey theme over a completely black one, it can be easily adjusted. Highly recommended!

The FF version works better than I had expected. It's darkifying many of my favorite websites in manner that looks like the site had its own dark mode. So easy to switch on and off too.

having white/black list is awesome. Indeed there are plenty of similar extensions, but this feature makes it unique

Works well, but does send telemetry back to darkreader.org (which can be blocked with Pi-Hole or AdGuard Home).

I have also assessed the source code of this extension myself and couldn't find any botnet libraries packaged with it. However, there is a similarly named extension for Edge which is packaged with them, but that is not this Dark Reader extension.
