Slows web pages to 2000 dial-up level

Makes website loading too slow. Almost unusable with modern websites. Dark theming is good.

This has been one of my favourite addons, ever since I found it. Hugely customisable and very handy. But lately it's the cause of lags and stalls. Firefox grinds to a halt just opening Wikipedia articles, for example. But as soon as I disable Dark Reader, everything works fine.

Turn being bad after the last update .. Forced work even with websites have dark theme

It change the others color like the words or banner, please only change the background to dark and make a slider to let people can decide they want to change others color or not.

many sites crash when this plugin is enabled. Like aliexpress.

Extension not working on Android and the developer doesn't reply e-mails.
On Android the automation simply does not work, be it by time or by location.

Extremely poor compared to chrome version. Will overwrite splash screens, not handle div borders (leading to white bars everywhere), works poorly with most websites. Better than nothing, but not saying much.

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....

Very useful but its really affecting Firefox's performance with its resource demands!
This is the second time I installed and uninstalled it because I noticed how much it kept slowing down Firefox!

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.
