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.

Great plugin! My eyes are not bleeding at night time. At last! =)

Great

This just saved my eye balls! It works awesome, Thanks! The only con is that it requests permission to see all my data on web searches. Why everyone feels the need to invade privacy I will never understand.

Works for most sites tolerably, however it breaks the kindle cloud reader (read.amazon.com) regardless of whether it's toggled on or off, and regardless of whether you put it in the whitelist or not.

Technically works, sometimes. But very poorly. I've seen other extensions do a much better job. This one basically has to have a custom stylesheet for each individual website to work properly, otherwise buttons are disappearing, menu items are vanishing, backgrounds are becoming transparent, it's not just changing the way websites look it's changing and breaking their functionality too.

Amazing! It offers a variety of dark themes, but even the default one "Dark mode #1 (simple dark)" is so good that I didn't really try the others. There is thought put to the color palette, it's not just pitch black but a lighter dark much more pleasing to the eye. Furthermore, the turn-off button is conveniently/easily accessible as there are some unavoidable cases when sites will be broken or incorrectly displayed.

However, I do have some concerns about privacy: why does it need permission to all our website data? Does it have display-customizations for certain sites so it needs to check at runtime which website is loaded?
If yes, ironically, the addons.mozilla.org is not affected by the dark mode :P
