life-saver for my retinas, HOWEVER
costs a LOT of ram. if your browser lags hard i gotta go to task manager, firefox and kill the sub-program trying to eat 12gb of my 32 ram. usually works for long enough until i gotta repeat 10-15 mins later

Works well on most websites, with or without tweaking. Prevents flashbangs even on "dark-themed" sites.

I *really* want to like this extension. It's got a lot of promise. But it's a huge resource hog, at least on my system. I have to fiddle with it on any site with even slightly fancy styling, so I can't really justify the performance dip. I tried switching to a CSS injector with some basic rules and it was more reliable and efficient than this. I hope (and have faith) that'll one day change, but for now I can't use this.

good

YEEEES lets go

Dark Reader has recently been causing me problems on various websites. The pages get stuck while loading and links do not lead to the linked content, but to the content above or below it. The following websites only work for me if I disable Dark Reader. I use Firefox and Opera as my browsers.

otto.de
zeit.de
github.com

A must have, it used to be paid before after a certain days (or maybe it still is on chrome) but now its the best browser extension to have, and works like a charm almost every time

I installed this extension on Firefox for Android, YouTube will not play frequently and I had to restart Firefox frequently. I didn't know this, so I suffered this inconvenience for 1 year and 5 months.

Awesome but fails to overlay settings (additional darkening) on Google search pages. This doesn't happen with the Chrome version of this extension.

Made my YouTube lag while I played games. Very Irritating be warned had to uninstall.
