it's a nice tool for me because my eye is comfortable with dark contrast always

Fantastic, essentially add-on after sunset

yeah baby

Good

The one you need.

One of the best and most versatile dark mode extensions out there.

This is simply the greatest browser addon after ad blockers and the undisputed king of all "universal dark theme" addons.

Fast, and does a clean job. Works with every site I tried. Bravo!

Me gusta que la adaptacion de color que hace a todas las paginas

its great but there are some buttoms and things you cannot see when addon is in use

I like it very much - but there is one little flaw. :(
The scroll bar on the right side for up and down is hard to see as it is too bright if the mouse is not there!
So one has to search it each time you want to scroll up or down :(
Another problem exists with local web pages!
On one hand I see as selectable options: null, null/C:, null/C:/Users, null/C:/Users/cas ...
But none of these options being selected changes anything?
On the other hand I see the menu from: Disabled to Default but again none seems of them is selectable - at least the page is black.
Finally under Global Preferences I found null at the end and there was simple CSS defined but it wasn't applied (in this case foreground would be silver not bright white) applied was the default setting which wasn't changed.

After a lot of tests of other similar extensions, I find this one particularly well done, that's why i'm leaving this review. I love that it handles clicked links (different color once visited), contrarily to most of the other similar addons. I only found one doing this, and it's not open source, with less options. Here, you can choose several methods of darkening, and apply them to different part of the same website or domain (if the global setting breaks only some pages), by URL segments (domain, website, page, subpages, etc). I've not found this depth of settings in other addons. The customization of colors for different elements is easy and when some could say it's not as "fancy" as other addons, the interface is very clear and intuitive. And I also like that it is open source.
Developer, really well done. Your extension is the closest to perfection for what it does, imo.
Could you check if there is a way to darken the menu of firefox (left-click one, and when opening a folder of favorites in the favorites bar)? I'm afraid it's a limitation in Firefox Quantum, if you can't do anything about it, i totally understand. You have my 5 stars anyway :)

Edit: thanks for the reply and advice! I already have the dark themes enabled, I'll have to wait until Mozilla expand it to these areas of their browser.
Edit 2: oh, high contrast. Brutal, but indeed it works. Thank you for the tip! ;)

Ну наконец-то! изменяет цвета даже в локальных сохранённых страницах. Не хватает возможность хранить несколько пользовательских тем. Спасибо автору!

Rápido e eficaz!

Работает как в простых страницах типа google translate так и в сложных как Slack или Facebook! :)
Легкая интуитивная настройка схемы. Единственно - мне не хватило выбора из нескольких заданных схем. Но может не нашел в настройках? В итоге изменил ту что была по умолчанию на менее контрастную.
Пользоваться можно! Спасибо автору!
Thank you autor! Very well application!

wow awesome look

this is best dark background extension so far for me.
some dark background doesnt work when I already used dark mode. like stock price night mode twitter's night mode etc... but this totally fine.

Just GUI looks not awesome but other things is perfect for me.
I couldnt find like this extension.

Loved it, but not to be newly installed any longer on mobile although still working on other devices.
