this add-ons completely broken after Version 4.9.39, you can still download old one in release page of github if you want.

I have no idea how this is a recommended addon. When adding it to Firefox, a tab opens up with what appears to be a book they are selling, unrelated to this addon. I reported this, and I would advise you to steer clear.

Breaks mobile browser

rubbish

As well as it works for the chrome bois (chrome, edge, brave), on firefox it is a whole other story. it makes my videos and scroll grind almost to a halt, it is extremely laggy.
What's more, it modifies colors within photos and youtube - it desaturates the youtube video for example - its so frustrating that i prefer burning my retina on random light modes at this point.

Stole web data using typescript code

It extremely slowes down browser. Tested on multiple devices

Slows down my websites!

Since a few times, I can't linked WEB.WHATSAPP.COM from my phone (QRCODE) and in turning off this add-on, it works at last. Please fix this, thank you

It only allow to change intensity of darkness / brightness and contrast. But a webpage with black background and white text remains with black bg and white text. Pretty useless.

slows down webpage loading time, very bad user experience on android

Does not auto detect if the website already has a dark mode like it does on Android firefox...

makes the browser unbearably slow on every single site it's on. sucks bc it's the only dark mode for android

As soon as I started using this add-on, the video I was watching on Amazon Prime stopped loading + was much slower loading. It also stopped the subtitle function from working. So, I uninstalled.
