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.

its best add-on ever made i am speechless to describe how the great this add-on is this add-on is 1 of the 2 reason which forcing me to use firefox... yes new version isnt as good as old ones but still unbeatable against other this kind of add-ons... and tip those who are saying few websites not working i dont know its true or false but if u use invert option on those webs & refresh its start working... hats of 4 dev... a prayer comes 4m heart 4 u bcoz of this addon

I can't believe what an awesome tool this is! I've been searching for a way to change web page styles when the inverted pages don't display properly. This is the absolute best extension out there to tweak dark or inverted pages. To make this tool even better, it has the ability to set a style for "not only" the entire domain, but also each separate page within a domain. It will support a "different" style for as many domain pages as you desire!

Hi,
The addon is very good. My sugestion is:
Is it possible to just mouse click on the addon in the toolbar to activate? Instead of having to mouse click the addon and then still do activate? Or better yet, activate by keyboard combination eg ctr + o or another combination?

Regards.

Don't want to put a bad rating because that was an excellent add-on, but unfortunately the latest version doesn't work well at all. It seems to break the layout of the pages for a second or two before actually displaying the final result, which is very annoying. Hoping that the author will find a way to fix this.

This addon is awesome on desktop and on mobile, and the crashing tabs problem with complex sites like the BBC one or TheVerge has been fixed with the 0.6.6 update. Kudos to the dev!
