This extension slow down your browser/crash. In pages who is already "dark mode" it will break the page making is frustrating. Isnt intuitive IMO. But the last straw was the addon changed my dark toolbar to grayish and white (when addon is disabled) and didnt saved my previous toolbar (I clicked to check what the function did). Oh well, to much hassle for now. I can see it having potential to be a great extension but for now I wouldnt recommend it.

Edit: 1 month later after disabling it I still have issues. I wish I never had this installed. I would understand something Ive downloaded outside the official addon page screw with my browser. But for an "official" and recommended extension I cant stay quiet and do nothing.

This extension will slow your browser down like hell...! At one point I almost switched to chrome thinking it was firefox that was the problem. Firefox would take nearly 10 minutes to start after a few days of installation of this extension. And even after the browser has started it would take decades to load the site. And suddenly every thing started working smoothly as soon as I uninstalled this piece of crap. A piece of garbage is what it is..! This should be removed from the add-on store all together if not improved.

How does one get the thing to work. Thought I installed it, but it don't do anything. Am I doing something wrong?

takes like a million years to load up

I've tried to give this add-on a chance twice. But, sorry, can't do it. It breaks Firefox constantly.

Ne se met pas en route automatiquement. Je dois à chaque fois aller le désactiver puis le réactiver (dans 'extensions') pour qu'il fonctionne.

Used to really enjoy this addon, but has been very slow and several sites have stopped loading sections properly since latest update

Ive downloaded this 3 times and it still wont work

Super cool extension. BUT: Recently it abuse the fact that clones got spread with malware. In the "Instructions how to detect it". The first step it they try to make money by telling you to install spyware like Honey. How does that help me to detect if I was infected? Seriously shady wall of text and bullshit and only WAY down the page they actually tell you how to detect it. The Chrome instructions do not work for Brave BTW, you can not click any link to the Chrome store so I am not sure how I can verify it in my Brave Browser now. In FF I got the real version but I mean the malicious clones would not show a warning about themselves would they? So I guess I am fine Brave also showed the notice.

Take too much resource on some website

No funciona nada. No cambia el color de las letras aunque cierre la aplicacion o reinicie mi equipo android. En fin una decepcion mas.

It's great idea, I probe it and I like it, but it doesn't works properly in my firefox, it makes it works slow, and I can't be waiting for a web because Dark Reader is working. ¡¡ What a petty !!
Es una gran idea, la he probado y me gusta, pero no funciona en mi firefox, lo hace trabajar lento y no puedo estar esperando a una web por que esté trabajando Dark Reader. ¡¡ Es una pena !!

So much lags, lags in many sites, also no updates....

hate that white flash it makes on Google.com
it makes my eyes hurt everytime

Today, my firefox refused to start tabs, they were crashing (facebook twitter etc.).

After investigating, Dark Reader was the cause, once disabled, my firefox is working again and much faster.

Must be something wrong with this extension.

facebook looks like absolute shit

No longer supported on mobile Firefox

It's nice, but it removes all my themes. I thought it was just a reader, right?
But dude, my regular default is gone.

Absolute hands down the best add-on to night-mode-ify the web.
BUT
It renders Firefox unbelievably slow.
