This extension has allowed me to get the exact high contrast look I want for websites, seemingly not available from any existing themes - at least nothing I've been able to find. For that I give it full marks. Unfortunately I have to lower my rating because it slows down Firefox to such an extent that I had to disable it again.

Makes YouTube look like complete shit. Makes other websites look like they're from 2003. It's hard to make apps like this look good on all websites, so the majority end up looking awful.

Always get this message:

Midnight Lizard
Settings application failed. Refresh the page and try again.
QuotaExceededError: storage.sync API call exceeded its quota limitations.

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 ? =)
