One of two things happened when I used this filter: 1. the screen went 100% white or 2. It gave an inverted color, in which e.g. buttons for routine g-mail functions became almost completely dark. I originally wanted to use this to improve the poor color (darkness) on a movie from Amazon. It was useless.

Too difficult to control the darkness and contrast. Also, after I disabled it the colors on the pinned tabs were not changed to their original color. They are purple

I have no idea why anybody likes this app. There are constant white flashes of death. By that I mean everything is cool and in dark mode, then you go to a page and there will be a full white flash to burn your retinas before the dark mode kicks in.

This is 100 times worse than not having dark mode! How is this helpful at all? I wondering how much eye damage this one "RECOMMENDED" extension has caused!

Makes the browser too slow and inusable

When i removed the extension, for whatever reason parts of websites are still dark, very dark. I have no clue why this is nor am I able to fix it.

The worst! Almost every site freezes and lags when this addons is activated. Impossible to use comfortably!

It's incompatible with some streaming websites, causing the whole browser disconnected from internet.

Extension updated and decided to apply itself to literally everything, took a while to find the culprit.

J'ai malheureusement dû retirer cette extension de mon pc car juste après l'avoir installé, l'extension bloque en permanence toutes mes pages internet à cause d'un script qui reste à travailler indéfiniment et ne veut pas s'arrêter et quand je demande à ce que le script s'arrête pour une page donnée il ne le fait pas et continue à perturber mes pages internet et à me bloquer. C'est dommage...

"Script from this extension causes Waterfox to slow down" and the CPU goes 100% for no obvious reason. No, thanks, moving on to the next extension.

Absolutely horrible. Runs scripts at the background to darken the pages, where a simple CSS-Edit shouldn't take minutes to adjust. Feels like having the worst VPN running in the background while scrolling a website.

Ralenti fortement le navigateur, si il ne le fait pas planté. Configuration : Firefox 78.0.1, Inel I5 7ème génération et 16 GB mémoire vive

I installed this ... everything slowed down to a crawl. My PC is no joke so this was a bit worrisome. This should not happen to this level of PC for a "color filter".

WORSE: I figured out why... When I installed this suddenly there was a new extra popover advertisement on youtube!!!! I instantly uninstalled.

The advertisement stopped happening after I removed this extension. DONT TOUCH unless you like extra advertisements! The injection code can explain the slowness. They need to mention they inject code for advertisements.

Its messed up to ask for donations AND advertise... Im going to report.

Good, but it's too heavy. My cpu fan of my notebook runs like crazy when loading pages. So, I revert back to 'Dark Background and Light Text'
