So far so (very) good!

"Dark Mode" works on all websites which is awesome compared, can be enabled in "Private" and is super simple to use; that little button in top-right corner is perfect.

Why not 5 stars though? Because the I think the black and grey "colors" used is a bit too much, I'd like pages to be a little more lighty, if you could say that hehe, so an option to make pages more light or dark would make me go 5 stars.

Pretty good for PC and Mac computer users to use on their Firefox browser. It's really almost perfect to dark mode on Android, I just wish this extension didn't use so much ram on the Firefox browser. . 4/5

This is the best one i have found so far Looks good :)

But the builtin styls only works on your website and not on FB :P (FB stays like in the image under no matter what)
And theres a white rectangle around messengers oval chat bubble

かなりのウェブページをダークモードにする。たまに写真や文字が背景色になり、表示されなくなる場合がある。

I am a developer and I am pretty impressed with what this add-on delivers considering the complexities involved. Every now and then it messes-up a web-site, but that's pretty rare and I think it's acceptable since the add-on lets you exclude certain web-sites.

Also every now and then the add-on inverts the colors of portraits and makes people look like smiling white-walkers. I actually find this endearing and it makes me laugh, better serotonin than eye-strain I say!

would be best night mode addon if not white flashes on page loading

Hello Bernard!
This is a good app for me! My only problem is that it is not compatible with Whatsapp Web website. The whole screen goes blank when I turn on the app. Please look in to it.

I like this addon, works better than other dark mode addons. I only two things I can fault with it, is it seems to give strange characters on facebook i.e. the letter 'S' will turn up as a '$'. Also emojis are on top of one another. If there was a way to turn off the other emojis in the app it would almost be perfect in my opinion.

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.

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.

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

great...need to add option to activate from context menu also

Simply the best dark theme provider - tried many others for individual sites but this one works for all sites and works great.

Edit: Some issues; it inverts gifs and other things on twitter so you're better off disabling it for twitter and using twitter's native dark theme

One or two other sites don't get along but you can turn it off for a second on those.

Would be nice to have a list of sites it's "on" for and "off" for.

Looks great, and also has clean and nice icons.

Seems to mess up some embedded videos, though (specifically Reddit and Vimeo).
