Display shuts off when streaming Netflix or Amazon Prime
When opening Netflix or Amazon Prime in Firefox 143.0.4 (64-bit) my display shuts off. This does not happen when viewing other video websites like Twitch or Youtube.
I can switch to another display port on my video card to get my display back, however, if I go back to either of those websites and login my display shuts off again. This does not happen in other browsers; I have tested Chrome and Brave. I have disabled hardware acceleration with no change in behavior. I have reset the settings of my browser with no change in behavior. I have disabled and re-enabled the privacy setting "Play DRM controlled content" with no change in behavior.
Why is Firefox shutting off my display when going to these websites?
