I was paying for Night Eye until I discovered this extension. It has a better interface than Night Eye and doesn't limit how many browsers I can install it on. I was very happy to send them a donation!

I LIKE MOZILLA FIREFOX

"Firefox recommended"? kind of joke? the import/export settings IS BROKEN = DOES NOT IMPORT THE SITE LIST, this little wh*re (the developer) has no idea to fix this, figure it out.

So convenient to use! It sometimes slows a page but worth it

Хорошо адаптируется под чёрный цвет, что мне как раз и нужно в темноте.

Causes Firefox to slow down and be unable to access any websites.

4.9.34 is the last version that works on my Firefox 56, so I'm keeping that one until a fix.
