It is the best of this kind. The default works on almost any website. For the very few that are not readable, it is very easy to change the method used to color the page.

Works very well with most websites, the ability to disable or change the method on each website makes it perfect. Now all websites can match the color of my soul.

Unfortunately, Firefox won't let me download this onto my phone anymore. Firefox claims I need a newer version of Firefox, but I have the newest version of Firefox. Furthermore, the link that goes to the "newer version" goes to the version I have. I know this isn't your fault. It's Mozilla's fault, but I thought you should be informed about the problem. So far, this is the only add-on I can't install. :(

On a side note: I still can't believe add-ons like this are still necessary, especially now that we have devices with AMOLED displays.

This is a good addon, but lacks some of the functionality I loved in dark reader for chrome. Namely, the ability to adjust brightness and contrast from the plugin. If I could combine the two, I would be totally satisfied. Also, PLEASE find a way to fix the bright white url loading screen! Another idea: multiple color schemes which can be applied at random to new tabs. This would aid in distinguishing tabs from each other, which becomes difficult when they all have the same scheme. Thank you!

Excellet! Very easy to use!

Very good extension, waiting for it in the Microsoft Edge browser, do you have forecast?

I love this extension so much. Simple, easy to use, customizable, and works on mobile too!

Extraordinary! Anyone that is struggling with what must be by now the largest problem affecting the internet-age people: light from the monitor tormenting your overused eyes, must use this add-on. Brightness will stop being your worst enemy.
It is simple to use and a relief to the eyes.
Best of all, it almost never brakes a sites' redability obscuring elements of the webpage, like many other colour or style changing options do. At this moment the very best of what is in offer for this specific purpose.
:)

I love it. Only problem is annoying white lines in some webpages. I am using stylesheet proccesor with Firefox 57+. (I do not know maybe because it is new on firefox57).

Works well (using in Firefox for Android and Desktop).

I see in the patch notes you're working on the white flashes, so just wanted to say thanks for your speedy updates so far and good luck taming this wild ff57 update.

Best and favorite addon by far.

And for all of you saying it doesn't change the homepage, read the patch notes, you freaking dummies! FIREFOX disabled ALL ADDONS on those pages.

THE SOLUTION (for now at least):
INSTALL THIS ADDON: https://addons.mozilla.org/en-US/firefox/addon/new-tab-override/
USE THE ADDON TO POINT TO A NEW CUSTOM HOMEPAGE FROM HERE: https://www.myfav.es/

FIXED.
