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

Simply Awesome!

perfect addon

Great color palette, but sometimes has weird functionality and/or doesn't always work. Examples: 1) on Facebook, with Owl enabled, Messenger is not functional (messenger window is hidden, and trying to access it from the list of contacts on the right causes the whole page to scroll down several screen-lengths). 2) very weird: some search terms disable the Owl extension on the Google homepage. Example: any search string with "pdf" returns the normal blazing-white Google search results page.

Summary: good in a pinch, but very buggy.

Clicking on the icon doesn't do anything.

Adds a button to the toolbar, but clicking it doesn't do anything. Enabling "Enable Owl at startup " in Owl's settings doesn't help either, websites still bright.

Generally a good extension, but unfortunately not available for Firefox Beta on Android.

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

Unsure how to add websites to exclusion list, right click context menu shows no option. Please advise

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.

Slows down rendering. (I'm using Firefox 57 Beta7)
I assume it's the same with 56.

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!

My last review had said about a problem however that was caused by it being disabled on a website.

However I wish I could still get the menu to popup from the icon (only turns it on and off T_T) instead of having to use the menu icon that is in the search bar. As the search bar icon does not show up if the plugin has been disabled on a website.
