Most recent update not working properly (as of Sept 23 2021). Not working for most websites. Worked great prior to this.

Works fine on FF beta, but not compatible with FF nightly for some reason.

Web Pages load slower with this extension even on my high end gaming laptop, and this is after the data has already been received from the internet for the webpage but the extension adds time applying dark theme to websites. Also extension consumes enough system resources to kick in my laptop fan when alternatives like "Dark background and light text" doesn't.

I really wanted to like this addon. It does the best dark mode and everything works good, most of the times. However, when my laptop is under load, this addon delivers the final blow. Firefox becomes soooo slow!
I highly suggest it if you are a casual user, but if you push you device to work hard you should avoid this. I am sorry. 3 stars.

Works well when it comes to the end result but slows the browser down considerably, pages take much more time to load.

La aplicacion es buena pero no funciona con todas las webs.

The extension does its job well, but with performance impacts.

Works really well, but it makes websites take 10 times longer to open up.

not working for all sites but it's ok

Love the look! But the resource consumption required for it to run was too much making for a very slow Firefox. Love the concept Alex... keep trying.

At first worked great, but recently stopped working on most of the sites, where I used it.

I love this addon but unfortunately on my samsung android tab the fusty performance is significantly reduced. Tabs tabs much longer to load. Details of browser and os below

Nice plugin, it's just a pity that it doesn't always work. Sometimes the color of the fonts remains black on a dark background, or the font is light but the background does not turn dark.
