Tried many but this one keeps me going on

Very very great for low visionusers!!!

It makes pages dark, but yet readable. It does slow FF down a bit loading pages as it has to parse them, but it does a GREAT job on pages. Love it!!!

You can take care of eyes.
You can save mobile phone's battery.

your add on is very intresting and very good. I like it and i start to use it, for now ,,,
as you already know, sometimes the code become heavy,
in some weak devices, or
in sites that are already heavy, by inject too much js code to the user.
Because of this last, and because most of the sites, start to become like this ( i mean put the
user to build the page, and not the server => thats why our browsers seems so incapable some times,
and take the CPU/Memory and create big swaps (but this is another discussion),
i want to share some ideas.

1. there you have your tabs background / images / texts /.... ,
give an option to disable any of them. So later your js to have less work.

2. This will work, In sites that have somehow very similar CSS selectors across their pages.
instead to inject class to query selectors through JS, compile a CSS by the 1st page of the site,
and then just inject the style, after the page load. I believe in facebook, youtube this will work
quiet well, and give an option to the user (maybe in Common section) to use this mode.

sorry, for my big review. Nice work !

Excelente Extensão

So great for my visual impairments and easily readable and convenient to locate information even at night in the car. I love Mozilla Firefox!! Best browser EVER!!

Thanks a lot, this was much needed

GREAT FOR THE EYES SPATIALLY FOR READING THANK YOU!

The fact that the web managed to embrace responsive design and utterly forget about colour is a crying shame. This extension fixes that oversight and makes the web usable in low-light situations.

Unfortunately, to do this, it needs to continually process the entire DOM, and for sites with massive amounts of information, such as big Trello boards, this is a big hit and slows down everything. As such, this shouldn't really be done as an extension: it should be part of the browser rendering pipeline.

MY EYES! I can see again :p
look through the settings, this one will
allow you to be off at all time, and run only on cretin pages.
Love it :D

Operacional

great

Absolutely what I want.

when these pages/sites complete loading the whole page gets dark and can't see anything.

--------
EDIT: / EDIT2:
:( I have no idea what it has conflict with. On github.com and en.wikipedia.org, it works fine for most of pages, but just gets whole dark page for a few specific pages likes I have listed above.

(Windows 10 1803, Firefox Developer Edition 62.0b12(64bit))

UPDATE: I've found the cause of this issue, Midnight Lizard conflicts with *Vim Vixen* on some websites or partial of these site's pages. But don't know who to be blamed.
Opened issue: https://github.com/Midnight-Lizard/Midnight-Lizard/issues/153

--------
EDIT3: P.S. When Midnight Lizard is enabled and dropped in Firefox's Overflow Menu, its option page is not scaled properly and it's hard to see anything.

Enfin une extension qui fait le travail correctement ! Fini tout ces fonds blancs éblouissants ! Comme Turn Off The Lights mais pas seulement pour les sites de vidéo. Le grand plus : tous les textes sont en couleurs adoucies, des blancs grisâtres et des bleus crépuscule. Si vous en avez assez d'être ébloui par toutes ces surfaces blanches, installez Midnight Lizard sans attendre !
