So far so (very) good!

"Dark Mode" works on all websites which is awesome compared, can be enabled in "Private" and is super simple to use; that little button in top-right corner is perfect.

Why not 5 stars though? Because the I think the black and grey "colors" used is a bit too much, I'd like pages to be a little more lighty, if you could say that hehe, so an option to make pages more light or dark would make me go 5 stars.

This addon is great and would deserve 5 stars. But unfortunately it still needs tuning and improvement. The addon is not working correctly on many sites with videos and pictures causing the media (mostly video) box to just show as a black box. This happen almost on every site (for example cnn). So I had to exclude it for all these sites.

Very good for healty eyes Thumb Up !!!

Pretty good for PC and Mac computer users to use on their Firefox browser. It's really almost perfect to dark mode on Android, I just wish this extension didn't use so much ram on the Firefox browser. . 4/5

有BUG，会导致在论坛回复帖子后无法自动刷新页面，找了好几个星期，没想到是这个扩展导致的。往修复。

Exactly for what it maded. Excellent!

This is the best one i have found so far Looks good :)

But the builtin styls only works on your website and not on FB :P (FB stays like in the image under no matter what)
