Magical It just manages to work with every website somehow. The comfort of your eyes. wow! All the screen time spent over a day adds up and this really is an eye-saver.. Email, Facebook, YouTube, Google.. all of these can't hurt my eyes no more!
This extension breaks more websites than it fixes. I didn't realize it was this extension that broke Twitch for me. Video stutters, freezing, etc. Many pictures won't load on websites with this on, either. Overall it needs more work/optimization.
