Love the look! But the resource consumption required for it to run was too much making for a very slow Firefox. Love the concept Alex... keep trying.

works decently on some sites, but slows my browser down a lot and breaks sites i visit fairly often - on firefox android

Can be a bit slow to load or mess up colors on some websites, but it can be adjusted in the settings.
Overall still very recommended.

As soon as I opened my Google Docs tab, I just easily mustered the feeling to say "woah, that's sick" to myself. This extension is incredibly useful for my eyes. Thank you.

At first worked great, but recently stopped working on most of the sites, where I used it.

Causes the browser to bog down and will cause it to stop working and shut down at times.

Using this extension I can decide what time of the day the extension will stay inactivated (morning and afternoon) and activated (night). Thank you Alexander!
