It works really great. The dark theme looks natural and clean. I really like the options for further adjustments. However it may affect the performance quite a lot on older systems, also it affects the elements that are displayed by other extensions.

Best of the dark theme browsers. Works great. Slows browser down greatly though. Took me a few weeks to realize this extension was slowing Firefox. I also tested it in Chrome and found Chrome was much faster without it. Please fix this issue. Other than that, a GREAT extension! Thanks Devs!!! :)

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!

There are many like it, but this one is the best. Although I wish there was an option to turn it on/off automatically based on time/location.

Muy bonito y funciona en la mayoría de páginas.

Bonjour, un grand soulagement pour mes yeux! Merci.

It's a great extension. Helps my eyes a lot.

But it doesn't work well on all websites. For example OneDrive on Web (Top panel bar on webpage remains white). It doesn't work at all for Outlook Mail (Web) [https://outlook.live.com/mail/inbox]

Just discovered this add-on and my eyes love it already! Allowed me to get rid of all my individually installed Stylus dark themes and then remove Stylus altogether, brilliant! My only gripe is that it turns my dark-themed about:newtab page light..? Not a major inconvenience I know, but if it can be fixed then this would be a 5 star rating.

great but slow down browser

Read stuff, really helped me move from chrome to firefox now that you added it on here. Thanks so much! Although firefox sometimes struggles to load pages, and blames a script within this extension. Guess early bugs are to be expected, since this is a recent addition to the store

It works very well on Windows. But the page doesn't turn dark on android.

you tub seed it was cool

Very good extension, the way background are darkened is clever and keep pages readable

nice addon.
but dark theme not work well on youtube.
i can not see seekbar

While using the new Beta Reddit, I have to toggle this extension Off then On to get newly opened posts to display correctly. Otherwise it's great!
