Works really well, fantastic!

Glad this add-on is back. The best as of April 2020. Don't even bother with the other ones, I've been through them all

O melhor de todos!

Excellent! Just what I was looking for.

It's amazing. I'd never have thought that it's possible to 'darkify' web pages in this quality. Almost like a horde of little, dark loving, aesthetically talented people living inside my browser.

That's great useful extension. Special thanks to the developers of that.

Thank you!
This add-on was very useful. it change the background to dark on every site correctly. 👍
