Works as described. No more migraines :) Wish it was available for Firefox for Android as well.

Looks great and natural! And doesn't mess up forms.

It is greate, just what I expected. Works with all pages and plays nice with forms.

Simply Awesome!

perfect addon

Colors are perfect after enable to the extension. We can set enable/disable status separately each websites.

Toggle button and ability to include/exclude particular sites makes this a very user friendly add-on . I haven't noticed any slow down. Great piece of code. The selection of high contrast colors are perfect for people who are tired of burning images to their retina with white screens. Save your eyes for astronomy. Thanks for the good work.

Nowadays some websites offer dark mode, but most don't. That's why I have used reader mode a lot, and finally had to find an addon to fix rest of the too light backgrounds. This does everything it needs to do. Only thing that I didn't find easily was the website specific controls: right side of the address bar.

Finally the white flash when loading page is gone in firefox 57 so it now works better than ever.
This addon is essential when browsing after dark and looks way better than global CSS styles, though I still prefer dedicated styles for most frequently visited sites.
The only complaint I would have is that embedded yt videos are in negative when switched to fullscreen. This doesn't happen when watching directly on youtube site though.

I was unable to find a way to white-list sites because I didn't noticed little owl icon in address bar.... Stupid me. This addon is officially absolute best for night owls like myself. Works amazingly well - I was looking for something like that for a long time, using multiple addons to fix look on various sites, struggling and bloating my Firefox. No need for that anymore. AND it will also work with upcoming FF57 which is great. Thanks a LOT tk! Amazing job! I will donate little something as soon as my paycheck comes and you all should!

This addons works almost perfectly, nearly everywhere. It almost makes it unnecessary to use dark Stylus styles.

Sometimes it weirdly and unnecessarily inverses the colors of images, but usually this just integrates seamlessly into the rest of the darkness.

This addon is like a dream come true. 10/10.

Use this frequently in Firefox to relieve eyestrain. Please port to SeaMonkey!

You are the master of disaster, mister! This one is masterpiece.

cool!
