Looks great, Slows browser

Cumple con el cometido, sin embargo, genera problemas: en la versión Android genera problemas al salir de Firefox, ya que se queda limpiando los datos. Si deshabilito este complemento, Firefox se cierra y limpia los datos al salir. En Firefox para Escritorios, muchas páginas cargan más lento de lo normal.

Is it normal to notice that web pages take a little longer to load? When I deactivate the complement I see that it returns to normal. I use it in conjunction with uBlock Origin and Poper Blocker.

Dobry, a nawet może być najlepszy, gdy zostanie poprawiony czas wczytywania stron w przeglądarce. Jednym słowem zwalnia Firefox.

This is the ONLY way to get all the buttons in GMAIL to show up properly when you hover over them. Friggin great, so far.

edit: it is slow beyond belief on some sites. reddit is totally unusable. my PC is very capable - i7, 32gbram, 1tb NVME. this is going downhill

全体が見やすくなりますが、処理が高負荷で低スペックのPCでは速度を低下させてしまいます。

this treats google.com and youtube.com as same site, i want dark reader "on" on google but not on youtube because youtube has its own dark mode.

Very good extension, but i can't recommend it. It sucks css and js from sites, so you will be banned from many of them without knowing where it comes from.

Although, it really slow down lots of sites. Prefer Stylish.

配色不错，但是在深色模式下无法看到搜索栏中输入的字，百度搜索栏，win10自带输入法

I really, really want to love this addon but it it has a single-minded inflexibility that makes it frustrating to use -- or it's hidden its settings well.

- It has Dark and Light options, but no 'leave it alone' which can cause a fair few problems
- It can't be defaulted to a 'do not modify a page unless told to' mode

This causes a lot of extra effort and can hide/mask/confuse conflicts and diagnosis when using other addons like Stylus, etc.

I adore the idea and it does a really great job at what it sets out to do, but it lacks some necessary operational flexibility.

Está muy bien pero últimamente me ha venido dando problemas graves auqnue desde siempre algunas páginas me indican que crea conflictos. Estoy buscando otra desde ya.

It can work pretty well at times, but it's far from perfect. Many a website will look quit poor, partly due to a lack of settings to tweak the exact colour alterations and partly because it misses certain page elements occasionally. I understand imperfections are to be expected, but since I would rather avoid ugly websites, it prevents me from using it on most websites I would wish to. I instead end up relying on custom CSS stylesheets, which this is meant to replace.

Отличная задумка 5+
При этом сильно снижает скорость загрузки сайтов и сильно нагружает ресурсы ПК.
Надеюсь, что плагин будет оптимизирован.

As others have said, this addon works, but the performance hit is just too great on Firefox.
Works well on Chrome, though.

As others have said, this works fantastically, but it slows things down so much you can't actually use it :-(

This addon has gotten much better but in the last week or so it stopped working on addons.mozilla.org. I have all the necessary about:config changes made to enable it to work with this site, but it just...doesn't. Was working fine before.

Ставилось для чтения переводов вебстраниц на translate.google.com. Панель переводчика конвертирует, но фрейм с текстом перевода остается в оригинальных цветах. Также, в отличие от штатного Firefox Reader View не позволяет задавать гарнитуру, кегль, межстрочный интервал и кернинг. Наконец, сепию считаю необходимым заменить или дополнить красным фильтром, для чтения перед сном. Firefox 66.0a1 x64, Windows 10.
