My Computer screen dims dark while watching Amazon Prime movies on Firefox.

Dear Firefox,

My Computer screen dims dark while watching Amazon Prime movies on Firefox. At first, I thought something was wrong with my computer, and after a series of attempts to fix the problem, I soon gave up and tried watching the Video on Safari and then Google; to my surprise, watching the Video on both Safari and Google my screen held steady and never Dimmed?

Some websites have a setting to darken the display during the playing of videos.

I have same problem. It's a new issue; didn't happen last 2 years on FireFox, and now it does. Using Safari fixes it.
