I suffer from low vision and Midnight Lizard changed my life. Unfortunately, as another user wrote below, a recent update is slowing Firefox to the point of making it unsuable. I hope the issue will be fixed soon.

firefox reports that it is slowing browser and asks to stop app. must uninstall.

Best night mode extension. Allows you to switch off without disabling the dark mode for the rest of the websites. Highly recommended!

better than DarkReader, but here are some performance issue in video website

so good

Very good extension so far, nice color schemes, etc. only problem is it makes certain websites take longer to load. no idea how to fix that, otherwise pretty nice.

Hands down , this extension is king , being able to have full control over what custom pages look like , plus the varieties it have beyond the dark mode and being able to adapt to any page designs is remarkable , kudos to you pavel

Pretty slow, but i use a 9 year old mac so i guess thats fine

Works on Firefox Nightly!

Sencilla y eficaz!
