Would be awesome if you had a 'light-dark' option too, that changes most colors to grey or dark grey instaead of pure black. This would help peeople working in dim lighting conditions for whom total black would be a little too much and cause more strain on the eye instead of reducing it.

This is my favorite dark mode add-on for Firefox (and Chrome) right now, but it still has some things to be desired, such as a time-based dark-mode, and the fact that it can't control the "theme" so the search bar is dark too, and things like that. Consequently this add-on pairs best with the stock Dark theme for Firefox, which is a bit bland to me. Also, this add-on (and the Dark theme) cannot affect the appearance of any sites core to Firefox like the Add-ons page (which makes sense from a privacy and security standpoint, but not from a user experience standpoint). I'd also like to have more control over the colors and adjustments than just sliders or CSS code or Toggle buttons. It would also be nice if it could darken the screen before a site loads because the flash of bright white after clicking a link is quite jolting and unpleasant.
Dark Mode for Chrome (and maybe Firefox?) has a lot more flexibility in that realm, but it's just not as quick or intelligent as Dark Reader.
Also some of my complaints are more at the way Firefox handles add-ons, so there's not a lot that the developers can do about those things.

How haven't I heard of this before, this is really useful dark mode extension, and the white mode is better with the dynamic option, I highly recommend it.

This extension is amazing! It really does help with eyestrain. It doesn't work on my personal website but it does work for all big social media sites and gmail. It will help on longer days where I have more intense workflows.

лучший. не знал что такое расширение есть на лису. респект автору

This extension slows FF down to a crawl which makes it unusable for me.
The dialog may seem intuitive, but when you have to wait for several seconds for the page to update, you have no idea of what's actually happening.
One star for the efford.

It is extremely fast at applying the preferred dark background's without any flashes.
