This and Vimium are the most important extensions I consider when deciding to use a new browser. I'm so glad Dark Reader is now usable on Firefox!

It is useful.

Used this on Chrome, because with four monitors, the flood of light became tiring. Now that I've switched to Firefox, I was happy to find Dark Reader again. Works great. Nice controls (not that they are needed often). I did notice it's possible to turn off just for a single site (Google docs shared JPGs required), which was nice. This work. Good work.

Works perfect, except on Youtube. I have a good gpu but when colors are inverted, Youtube videos lag heavily. Have to turn it off for youtube, everywhere else it works fine. CPU usage also goes to crazy 30% because of youtube on invert. Please fix.

Edit - Contacted the developer, gave me an extremely helpful reply. Will be resolved soon hopefully.

Класс, все четко работает

Is an improvement on the dark reader I was using previously in the following ways :
1. colour scheme is truly quite intelligent and much easier on the eyes than simple inversion
2. the menu for controlling the extension is well-designed, intuitive and looks good

Cool. but how do I turn it off?

Cool!

Жутко тормозит на мобильной версии Firefox. Хотел с планшета почитать сайты, но не тут то было! Так как для мобильной версии Chrome нельзя устанавливать расширения, то специально установил мобильный Firefox и это дополнение. На моём Asus MeMo Pad FHD10 страницы грузились очень долго, прокрутка практически зависала по несколько секунд. На десктопной версии проблем нет.

White screens kill my eyes.

Awesome app

Not working!

Exactly what I need in the night. Many thanks!
