This is hands down the best looking dark theme extension for Fire Fox that I have tried. Out of all the other ones I have used, this one manages to do the best when it comes to picking the right color schemes for websites. Alexander really has a knack for colors!

Unfortunately, Dark Reader, like a lot of the dark mode extensions I have tried, has a huge performance problem. This is most obvious on sites that have a lot of JavaScript or are using newer technologies, from what I have noticed. FaceBook, Amazon, Verizon (to name a few) slow down significantly when using this extension.

Also I have noticed Dark Reader is not perfect at reskinning web sites. I have had it glitch some sites out and cause them to look really weird or unusable. These are of course edge cases, but the longer you use the extension, the more you start to notice it.


I have tried Dark Reader on numerous computers, and unfortunately all of them end up having the same problems. So, alas, I will probably not be having the cool little Vader with glasses gracing the upper right hand corner of many of my browser tabs for a while. If these performance problems get fixed, I definitely will increase my rating.


None the less, this probably is the best dark mode extension there is right now. I really hope that the performance problems can be fixed. I have heard they are not as bad on Chrome, but if you are like me, that's not really something to consider.
