At least 4 times faster than Dark Reader. I dunno if it's bcos this is done right, or if DR is crap, (or both). You just need to know, I'm sticking with this one.
5 stars if I stay with it for a month.

No funciona nada bien con facebook

Whatsapp wird dabei leider komplett schwarz.

I really liked this app, the only problem that I have is when I'm in wikipedia and some equations doesn't appear because they don't change color, probably the problem is that the extension recognizes this equations as images.

Well, the extension does an excellent job "darkenizing" most of the sites without losing readability.
But it does the reverse if applied to already dark-themed sites (either natively or via a Stylus theme). Also, sometimes text becomes unreadable and/or images invisible after applying dark mode. Manually whitelisting all such sites is cumbersome.
To deal with these issues, I would prefer any of the following mechanisms in this extension (or even better, all of them being configurable):
(a) have different mode for each tab;
(b) save last used mode for each site and apply it when opening it next time;
(c) use a list of sites to apply dark mode to (rather than not to apply it).

most of the sites work perfectly, please check for "web.whatsapp.com" , the complete page becomes black without any color inversion for text

Almost perfect. thx for your work.
But doesn't work on youtube live chat webpage.

Great extension

Conflicts with websites that already have a dark mode like, twitter, reddit, and youtube

逆天神扩展，太好用了

Very nice! Not sure if it works on all sites but, so far so good. I recommend! No one deserve white pages...

I have tested ALL relative extensions and I can assure you that THIS is the one.

The fastest, the most beautiful, with only one drawback for novice users. The manual way for custom modes. A CSS tutorial is recomended for such cases.
