I gave the extension a bad rating because it worked bad for me and I found a solution that worked better for me by using Wikipedia's own dark mode in Preferences > Gadgets. The rating is solely based on my own experience for my specific use case.

The author then proceeded to look up my user name on social media, stalk me there, made me explain myself, and then went on telling me that my personal experience is wrong because other people have other uses.

This was exactly what I'd been wanting for a long time, but never taken the time to see if it actually existed. Thank you.

Wonderful to have this extension! Only problems are that it often momentarily displays the white standard for a splitsecond before it turns black, and that links to non-existing pages are now blue like all other links
