Functionality is good, but it freezes or really slow down the Firefox. On mobile it's unusable, on desktop it ruins the performance. Even on sites with disabled filter.

I still remember how great it was when it could actually auto-detect site theme without relying on OS theme...
And there are STILL bug when if you switch auto -> on -> auto that it'll discard saved options and will default to "OS theme" even tho it's not even checked

llevaba usando esta extensión años. Pero he detectado que cada vez que se usa esta extensión los requerimientos de potencia a las GPU son enormes. Os invito a abrir una web con un numero importante de enlaces. y abrir en paralelo la monitorizacion de la carga en la GPU. activar y desactivar dark reader moviendose hacia arriba y hacia abajo en la propia web(sin necesidad de click nada) y comparar como de un 20% pasamos a un 80% en la carga de la GPU (mi grafica es una RX6700XT) .

I like the addon very much, but the webpages are slowed down by a factor 2 or 3! So no thanks.. It's just too slow.

Every time there is a firefox update I have to remove dark reader and install it all over again on my several firefox installs. Very annoying.

Not great. Just inverting colors which makes images appear inverted as well. Was hoping this was a true dark mode.

was great. now breaking lots of pages- wikipedia, and links open in new tabs.

linux based firefox 120 64bit

why don't all websites offer dark mode?

While it works on some pages, it breaks many pages for no reason. Some buttons cannot be clicked anymore, some text blocks disappear, ui elements get moved around and other problems. On the most recent Firefox version some tabs just constantly crash. Nice idea for a plugin, but it does not work...

Automation is broken when used on Firefox for macOS. When the extension is set to follow the system dark theme and macOS is set to "Auto" instead of "Light" or "Dark", Dark Reader mistakenly thinks the system is set to "Light" no matter what time of day it is.

Downloading any of the past 25 older versions of the extension doesn't resolve the problem.

The Chrome version of this extension has no such issues.

Lately it interferes with too many websites. So many sites, especially for news, use the "read more" button to see beyond the first paragraph or so, but I can't click it. I have to disable this addon before it works. I wish dark mode were more of the default across the web because it's so much better for your eyes.

The detecting of a dark theme on a website rarely works.

Dark Reader has one of the most confusing user interfaces I have used. It is completely unfamiliar to any other software I use on a regular basis. I can't tell if any of the settings are in the on/off enabled/disabled state due to ambiguous design. For example, a button shows either x or ✓. Does x on the button mean I'm switching to x by clicking or does it mean x is the current state? Another toggle uses a left/right instead of x and ✓. A third type of button uses x and ✓ but it's only on the left side. Then there's the light/dark flat buttons which I fail to differentiate. Does light mean pressed or does dark mean pressed? There is a complete lack of predictability and logic and I can't understand how I'm supposed to use it. I'm looking for an alternative extension.

Lags some websites into the ground making it unusable.

This extension slowed down my browser something fierce. It also doesn't detect when a site already has dark mode enabled like it used to

Would be an outstanding Dark Mode add-on - if the auto setting worked. It used to up until a year ago. I'd love to see it fixed!

Was working excellent some time ago, but recently stopped working for basically half of all websites I visit

I'm not sure if the interface changed and I just can't find the option but it appears that the custom colors option is now removed? That was the main reason I used the addon. I really hope I'm just missing something here.

Works in many cases but fails to distinguish between domains and sub domains.

Midnight Lizard works more consistently

Horrible slow down in page load speed with this plugin. Took months to figure out as it seems it should be an innocuous plug in. If you're experiencing slow page loads, try disabling this plugin.
