Excellet! Very easy to use!

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.

Love how easy it is to use and tweak to your liking, by far the best of its kind.

great application,i use many years but white flash killing my eyes .Please fix this .cheers

add support for ff 57 pls

Excellent!

Neat addon, but newest version has a disappointing effect: every time a new link is opened, tab becomes white until a site is loaded. Please, fix it soon.

Best wishes.
