makes pages negative rather than real night mode

Ive been looking for an addon like this that doesnt break one thing or another for a very long time. Right out of the gate, I can ACTUALLY see the day highlight on google calendar, and looking at it with a variety of other sites I use on a daily basis hasnt shown me any issues yet.

GREAT JOB!

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.

Night Mode Pro for Firefox - VERY good! :D
Fast and lightweight :)
Better than all others which have to"render" pages.

Improvement suggestion:
Make specific sites automatically switched on/of, add/remove from whistlist by day time :)

Improvement suggestion:
In Googlemail i can not see the buttons delete, archive aso. :(
Perhaps you can change his? :)

You need a Facebook-Page to like and repost :)

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.
