I've been using this extension for several months and believe it has great potential. With the release of Firefox 63 the page load performance has significantly decreased. Keep up the good work here, and I look forward to future improvements in performance!

It looks great, the color are nicer compared to other night mode add on! But it affects load times on some site. It could be the problem with my pc but I don't find the same problem with dark read on chrome.

Breaks the least amount of websites and has the least performance impact, at least in my experience. The stylizing is also pretty tasteful and reasonably true to the original pages. I did like the function/appearance of Midnight Lizard even more, but it was just too resource intensive.

i want to love it but it makes everything unbearably slow

wow 1 ère fois que je ne trouve rien de négatif a dire sur un plugin thème tout simplement parfait tout les éléments des sites web s affiche selon les paramétres choisi travail de maitre !!!!

Great extension, but with some minor issues.
I set up a black squat theme on Firefox, but every time I restart my browser, Firefox's main page will change back to bright. I think this is caused by this extension, I hope you can fix it, thank you!
In addition, in the search engine of Baidu(www.baidu.com), it only works on the first page, and all following pages are changed back to bright.

Interferes with Firefox browser, not enough customization for prime time for me, and as everyone else mentioned, it slows performance.

I think this is the best add on for changing web page color :D

I like very much the keyboard shortcut resource. Thanks!

The performance is extremely poor. The browser slows down of a great deal.
