Excellent extension since it works very well it changes the colors of the page, the brightness and the contrast to increase the readability and it brings the night mode is acceptable for its use.

Terrible, doesn't even overwrite CSS for background color of google tabs.

Midnight Lizard causes white flashes when browsing... (the "Dark Reader" addon does not.)

App doesn't work in reality... works on sites like google... newegg and a.co but when you try and scroll down on any of these sites the page rips locks up then firefox warns you that the app is locked up. You can hit stop each time and it will load the page but thats not what this is for...

Basically i would avoid this because its broken there are other addons that actually work...

Thank you for providing this extension Pavel

Better than Dark Reader!

Удобное приложение, можно быстро настроить и не ковырять настройки, и выглядит приятно. Автор молодец.
Приложение не вредит моей безопасности ? =)

Works great in theory, but not even remotely in practice. The addon doesn't remember my settings between tabs, which means that sometimes the addon doesn't active on tabs when I've turned it on, and is still active on tabs when I've turned it off.
Even worse than that, sometimes I'll change tab and it's seemingly just picked a palette all by itself. I set Midnight Lizard to "Apple Mint", only to open Youtube and inexplicably see it in "Sunset Sails".
My last problem is what everyone else mentions, in that it slows my Firefox to an absolute crawl. Both loading times and actions on the pages takes ages.

With a few tweaks, this seems to run better than Dark Reader etc. And it works well on mobile too. The many setting options may seem daunting, but worth it all the same. I especially appreciate the option to schedule Dark Mode both based on the System Theme and independent of the System Theme. Very nice.

THIS IS THE PERFECT EXTENSION IVE BEEN SEARCHING FOR MY WHOLE LIFE... it even has a green on black option, omg.....

Exactly what I needed

Today is my first day using this extension. Overall, I like it. I can tolerate that it's slower than Dark Reader, due to the fact its more customizable in my experience.

One issue I'm having is that some websites it wont remember when I apply "automatic" or "complex" filtering, etc, so the website looks as I would like it to. Is there a fix for that? Hitting "apply" doesn't make it stick, and I don't want it to become part of the default theme, as "automatic" runs best for most websites so far.

Hopefully in the future it runs better! No more white section on google images is definitely a win!! : )

Edit Sept 22, 2021; I see, Thank you! I'll see what I can do about the unnamed color scheme.

Not sure why, does NOT run well on Trello. Other websites, the delay is alright, but Trello locks up on me. Just be aware of that, other users, if you also need to use Trello. I still like the app, though.

4 stars for the response.
