Really, really, really bad performance on every website. If you like the speed of your browsing to go back to Dial Up ages, install this Extension.

Also, I don't understand why half of the options do not work. "Ignore-List", as you called it, does not work. On multiple occasions I try to add a domain, and it still does not ignore it and still makes it dark.

Also, why isn't there an option to enable this only on the website you are, and not everything on the web. If you want this extension on, you either have to turn it on for all, and then fiddle with that buggy not-working "ignore-list". Can't it be a "Whitelist", to be used by the extension, not an "Ignore List". This is the stupidest implementation of a feature I have ever seen. Why can't I choose the sites I want this enabled for, and I instead I have to choose for which I want it disabled. There are a lot of sites that have dark mode features built into them, and I have to go through every one of those, add them to the ignore list, and then find out that the ignore list does nothing. What a waste of precious time...

All in all, I slowed down my performance for weeks now because of this shoddy extension. There are other extensions that are simpler and faster and will do the same thing but will actually work without making your every day tasks a living hell.

I have actually been following this since a lot of time, and it has gotten worse now. The developer clearly likes to put on fancy features that boggle down your hardware resources, instead of making them work.

This extension breaks more websites than it fixes. I didn't realize it was this extension that broke Twitch for me. Video stutters, freezing, etc. Many pictures won't load on websites with this on, either. Overall it needs more work/optimization.

It does its job, which is to turn dark mode on for all websites. But it really slows down the browser too much.

As another user suggested, I'm using Midnight Lizard now which is more highly customizable and it doesn't slow the browser down as much as Dark Reader.

Slows down browsing big time. Not recommended.

Absolute crap, told it to not run on specific websites "Facebook.com" yet it would keep turning on and blocking content, do not download as it does not work properly and it blocks content...

If you are experiencing slow web page loading then this extension is the culprit.

Slows pages horribly. Often very slow to toggle dark mode.

Não funcionou no meu Samsung j2

So painfully slow as to be unusable, and frequently becomes unresponsive.

Extensão pesada fazendo o sistema travar completamente.

featurewise it's a good add-on but it's slowing down the surfing so much i had to deactivate it.

3 étoiles noires serait plus juste

ralenti la navigation
impossible de basculer jour/nuit ( c'est pas prévu)
impossible à désactiver
impossible de supprimer

Very very very very slow !!! I uninstall !!!

Extremely poor. Veerrry slow. Completely useless. I've never seen such a slow running software. I do not think this developer has the talent for software programming.

removed this add-on because I started getting Fake iPhone X for a $1 scam pop-ups in the Firefox browser.

works but too slow, 10 seconds to show a web page?!?!

Let me get this out of the way: It's very well-designed. It does exactly what it says, and it does it in an intelligent way. It actually looks like an official dark mode on every site. The only problem is I can't use it effectively because it murders your CPU and nothing will load. And it's not like I'm on a Pentium 4 that can barely handle Firefox itself, I'm on a $200 hexa-core from 2 years ago running at 3.9 Ghz.

In short, it's well-done, but it's so poorly optimized it's virtually unusable. I would gladly go back to it if I could actually use it.

nice mode but sometime memory leak over 6gb of ram especially when u go to EA website

works on some sites, but made gmail unusable and some sites stopped loading.
