It looks great on most websites and really helped with my eyestrain and I haven't had any issues with exessive CPU usage. HOWEVER it does break several website to the point of getting "Access denied" errors that were only resolved once I removed this extension. I will gladly return once this is fixed

É muito bom, mas quebra funcionalidades! Os arquivos e planilhas do GMail, dentro dos e-mail, não abriam ou demoravam MUITO para abrir a janela de baixar quando o Dark Reader estava ligado. Então removi a extensão e parou o problema.

It does what it says it does, however, it increases page load times by an unacceptable amount. Pages load instantly with the extension disabled. With it on, load times are anywhere from 3 to 5 seconds. That doesn't sound like a lot until you're sitting through it on every page load. And those 3 to 5 seconds add up after just a few minutes of browsing. Honestly this extension shouldn't even have to exist. There's no reason Firefox doesn't have a native dark mode like literally every other browser does. I thought this would be the fix, but it comes up a little short for me.

Used to be five stars, but Dark Reader is slowing Firefox down far too much these days... :(

Unfortunately this ext has been unusable of late(2/25/24). Firefox (on more than 1 occasion) suggested I disable it to improve performance. Slows down site loading, freezes and missing items are a constant now. If it returns to it's previous functionality I would happily reinstall as it was great, but until then, it has to go for my browser to remain functional. Hope a fix is incoming....

worked great in edge but in firefox it always flickers and messes up ui in many pages like facebook messenger

it's good, but why the hell it takes half of my cpu resources?

Almost doubles Firefox's CPU usage. It was causing stuttering on a stream I was watching. Awful performance, isn't worth what it does.

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.
