Самое лучшее расширение для отображения символов на черном фоне. Комфортно просматриваются большие тексты. Глаза меньше устают.
При этом в настройках можно быбрать
параметр -> (Изображение, графику не инвертировать). То есть изображение и графика просматривается в обычном виде.
Из всего опробованного, это расширение лучшее. Рекомендую.

It works well. A big advantage of this addon is that it has an option to keep images in their original colours.

Perfect for those websites that seem like the Sun when you look at them. Not too flashy and straight to the point; no special other stuff. Great job.

What can I say, it inverts colors. Awesome if you have vision issues with contrast or photophobia. I will donate on my next check thank you "max".

very simple, works very well

Great extension. Thanks. I am using this for pluralsight.com videos which have white background and none of the darkmode apps work.

One concern I have is - when I put the video in full screen mode the color inversion doesnt work. I have to do an F11 to make firefox fullscreen instead to make it work.

finally I found the one

I can't thank the dev enough for this add-on - I have a chromatic astigmatism that makes it incredibly difficult to read certain colors, particularly a color blue that seems to continuously pop up in the most inconvenient of places online. This is a lifesaver, especially since I can access it directly from the right-click menu!

I just want to say Thank You to the developer, I have crazy sensitivity to brightness and this extension saves me a ton of headache and I love you

For me, white text on a black background is very hard on the eyes. After just a few seconds of reading such text, I can see ghost images when I look away. This extension now makes those pages readable!

Excellent addon. It's possible invert color for each tab.

La extensión es buena sufro de la vision y desde que la instale mis ojos no han sufrido ha sido un alivio doy gracias a sus creadores

Simple and effective, it's what I want.
