The best extension for vision protection, fully customizable, I have set it up almost without any blue, and it is best for the eyes, thank you for this excellent application.

Asking for money for a simple dark add-on is simply unacceptable. There are many other choices for free.

I would avoid this addon. While it works very well, as advertised, the developer charges money for it after a 3 month trial. That would have been ok with me, except it's a subscription-based model. Very ridiculous. I would have been ok with paying maybe $5 (which is fair for what it is) for an outright lifetime license. But anyways, I recommend for something similar, try using the addon called 'Dark Night Mode'. It's similar and works well out the box, has a higher rating, and is fully free. For something with more features and customization, I really like 'Dark Reader'.

Messed with pictures and layouts, also with some extensions, for example greasemonkey, couldn't use it at all and setting of night eye were also not functional. No-go for me

Does apply night mode to websites well but loading times are hit pretty hard. If the developer can optimize that, it would make for a great extension. If not, not worth the load delays.

Really helpful when working at night or in rooms with not enough light. Amazing!

Great. I've tried all the other alternatives. None of them match the performance of this one. This is the best out of all. Please keep updating it regularly :)

I cannot work on my laptop without this extension anymore. It is that good!

The extension is working like magic plus the support was very quick to react and friendly. Keep up guys!

So far the best dark mode extension I've tried (and I tried them all!)

Best extension for dark mode! Thanks for the porting to Firefox! :)

Perfect for reading/working late at night. My eyes are really thankful!
