makes pages negative rather than real night mode

I want web page to darker only specific domain, not for all as default. So its need a list to dark color for the linked page- which is listed. And others all are non-darken.
Huge number of domains can visit by users. Yes, users who wants it always switching on/off for any site with their white list. And but some request is nearly same-that is, which users never need to use this darker software. But only for (suppose-) facebook, instagram, twitter, gmail, example.com1 ,2, and 3 (this 7 domains). He/she needs the list up. So two mode/group for list: 1)white list-not to darken & 2) Off mode- to perform darkening(for listed up) when switched off. And here, can disable option also be set.
Then users can disable extension or delete list as needs. If this possible system have in an extension- please reply me to define. I found nothing since two years to get it. Thank you

I have great hardware, & Firefox was running smoothly before I installed this. After doing that, I started to scroll through websites and it almost froze my computer.

Already an awful product that routinely makes websites unreadable, I had disabled this app and hadn't thought twice about it until it began to make random popups asking me to donate to the creator. The creator should be banned.

You tube blue and white,freezing on youtube,when you changing tabs, white page blowing In your face waking everybody for 2-3 sec...but main problem youtube not compatible at all,not working ,no way to watch..
