I've been using it for a while but there are always some issues.

Right now, on FF 90.0.2, it refuses to disable on certain sites (like Unreal Store).

The "Synchronize Site Fixes" and "Enable Settings Sync" options are completely broken. Every time I turn them on, they either turn off or remain on. One thing they DEFINITELY do, is to disable all my custom settings for sites, EVERY SINGLE TIME.

I understand "synchronize" option might be importing custom settings, but why would you even make such an option that wipes out all custom user settings without a dialog box confirming it?

OH you want to remove a specific site from a list of sites in the add-on? Well, I hope you like scrolling through a tiny list of sites, and thousands of domain names since this add-on never heard of a "quick search" option.


This is terrible UI/UX issue as well as bugs that haven't been fixed for ages.

The only option to preserve custom changes is to routinely manually exporting site lists and importing them every time you discover another broken site.

This add-on glitched my account and now I have white text on white background if I don't use the add-on. Switching from light mode to dark mode affects all my pages. Would not recommend and I'm looking for a way to block this add-on and it's effects from my browser.

DARK BACKGROUND AND LIGHT TEXT is soo much better! More customizability and most importantly DOESN'T SLOW DOWN OR BREAK PAGES!

Slows down webpage loading by a lot
which something like Dark Background and Light Text doesn't do

When this extension is turned on, it often takes a very long time to open certain pages, making it a completely useless garbage extension.

change the theme of firefox everytime I close it.

it works perfectly, but it slows down the web completely

Я то думал, что у меня комп стал медленно умирать, что аж думал надо винду переустанавливать, а оказывается что-то сделал разраб, из-за чего прогрузка стала долгой, не знаю какой у вас должен быть комп, i5 9600 16gb 2400 и тип не тянет такой плагин, смешно.
Плагин полезный и очень удобный, чтож придется привыкать к свету, спасибо за проведенное время

Its a good dark mode enabler for all websites..But it is making websites slow down..Its like monopoly..There are no good alternative like this and have to suffer..

Caused my browser to slow to a crawl.

При активации на Firefox влияет на скорость прогрузки сайтов. Без него открывает моментально, с ним оооооооочень долго.

Completely killed my browser performance, even after disabling and then removing the addon. Closed the browser after that and saw my CPU maxed out and my RAM being flooded to the brim until all background tasks were shut down after a while.

Didn't work for me.

This addon is a big joke especially on mobile devices. Bad optimization and the fact that the settings don't really work at all, I'd have to manually fiddle all the pages I visit if I wanted this app to work like it's supposed to work. Kinda big job to do that on mobile device, just gonna uninstall this and waiting for the day team Mozilla bakes a dark mode themselves in Firefox OR gives us more addon options like on desktop version.

slowed down my whole computer, uninstalled.

I've installed, uninstalled, restarted Firefox but Dark Reader is MIA. Perhaps I am doing something wrong but I cannot fathom what.

Works fine on some sites. For example on Youtube. But on other sites the tab hangs. And the whole browser slows down.

It slows up almost everything. I dont know why its recommended really. Makes FF too sluggish and slow when you open new sites or change from tab to tab.
