Wanted to add a couple of screenshots to show you the issue and it would have been easier to explain. Long story short, works well on most websites, but on few websites the color of the fonts makes them really illegible.

Please add roboto slab in font options

This add-on is a blessing for us people of the night.

Automatically change websites to dark themes based on your system settings, your real location or by setting a time frame yourself.
It works very well but in case you're seeing incorrect or annoying colors you can customize the theme for general purposes or for a specific website.

Very reliable.

This is a really good plugin! Works so well that sometimes I don't even know its on! ONLY problem is that, quite often, it darkens QR Codes (such as 2FA creation QR Codes) in such a way that they cannot be scanned and it can take a bit to notice that its DarkReader causing the problem. Amazing overall though!

Looks like it makes Firefox to heat up my Mac (?).
Firefox 122.01 on MacOs 11.7.10 (BigSur).
As soon as I deactivate it, the temp goes down to normal.

May cause increase in webpage loading time, try disabling this extension if your browser keeps getting "The connection has timed out" error

worked great in edge but in firefox it always flickers and messes up ui in many pages like facebook messenger

Tolle Hilfe für die Augen, wenn man mal wieder zu lange am Smartphone oder Tablet auf das Display geschaut hat.

This should be integrated into the next Firefox release, IMO :D

it's good, but why the hell it takes half of my cpu resources?

спасибо доброму человеку, кто придумал это чудо

Dark screens everywhere are a must have.5 stars

This extension exceeds all my add. The interface is simple and convenient

Шикарно. Просто выручил этот плагин!!!!

Almost doubles Firefox's CPU usage. It was causing stuttering on a stream I was watching. Awful performance, isn't worth what it does.
