Why it's so slow? Significantly slowing down using Firefox at all! Much slower than other dark mode addons, why? Please fix it otherwise it is not useful even when the quality of websites looks great.

这个功能很棒，深色系确实很舒服。但是问题是，网页加载的一瞬间还是有白屏闪现，就像CSGO丢了个高闪一样让人无语！！！....

Awesome extension. Doesn't support FF 75.x :(

The add-on does its job. Mostly. Well, rarely. Try it at AMO. It does not work. No dynamic theme creation is evident, just a huge static style for numerous web pages. How to change the dark theme? I hate that dark cyan. The add-on is a great collection of dark styles, no more.

I've been using this for years, and suddenly today, 2/28/2020, its being disabled? Please fix this, I can't bear to look at white screens anymore

Though it changes the colors of the site, it's not really a reader; tiny text remains tiny. It's just a dark theme. Also, the dev tools button doesn't work.

Makes the new tab page white which is very annoying. Otherwise great extension with lots of customization.

It does the job, and there are (currently and as far as I know) no alternatives. It's VERY resource intensive, and constantly slows down pages. I therefore only have it active on my gaming computer (a beast) and have deactivated it on my work computer. If you could make this less resource intensive, it would be 5 stars.

Aparece con demasiada frecuencia un mensaje de script que no se resuelve correctamente y enlentece el navegador. ¿Para qué es ese script? ¿Qué estáis haciendo otros usuarios ante esta situación? Gracias de antemano por ayudar.

Хорошее расширение, очень понравилось, особенно возможность автоматического включения по заданным координатам. Но, как водится, но:
Регулярная надпись "Сценарий в расширении Dark Reader замедляет Firefox" и, что характерно, ведь правда замедляет. Иногда при включенном расширении сайт вообще может зависнуть вместе с браузером на пару минут. Да, я понимаю, проблемные сайты можно внести в исключения, но это же не выход.
Собственно, из-за этого такая оценка.
Кстати, если кто думает, что в chrome как-то иначе, сюрприз! Все тоже самое. На тех же сайтах. И да, комп у меня не слабый и система стоит на ssd.

this add on completely messes up the layering on websites like soundcloud but it works for the most part on other websites

Works great for lightweight websites but slows tab or the browser to a crawl on most websites. Amazon was a concern with this as it would lock my browser up to the point I had to exit out of it. On Chrome based browsers this works amazingly. Oddly it's a different beast on Firefox. It seems to have gotten easier thanks to the latest Firefox updates.

Would be great if it didn't randomly switch off or just eat up my CPU and RAM like bacon on breakfast. I switch it on and my PC goes wild!

UMSTÄNDLICH! Wenn ich auf das ICON klicke, sollte Dark Mode ein oder aus. Aber jedes Mal wenn man auf das ICON klickt, muss man das erstmal im Kontextmenü ändern. Das ist zu umständlich. Ein klick oben sollte reichen. Und wenn ich irgendawas einstellen will, eben unter Einstellungen

It is a good plugin in concept and does what it says and has 4 modes which one way or the other make sites work with dark color profiles.

Alas! In many instances, especially sites with a lot of media or large animated pictures, it makes my browser either slow to a crawl or completely locked up for many seconds. Opening many tabs in short stints becomes a nightmare in such cases.

Especially when it first got installed (I had about 12 tabs open), it locked up my browser for more than a minute.
