When Firefox opens my display dims. What is the fix to keep the dimming from happening?

Regardless of what programs I have open, every time I open Firefox my display dims. When I log out of Firefox my display brightens to the way it was before I opened Firefox. I am running Windows 10. Once the display dims it remains dimmed even if I toggle to another program that is running. The only way that the brightness is restored is if I close Firefox. What is the fix for this issue?

Hi JC. This is likely a Windows related issue since Firefox does not control the brightness of your screen. It's likely caused by Windows 10's Adaptive Brightness feature.

Try this:

  1. Open Settings
  2. Power Options
  3. Change Plan Settings
  4. Change Advanced Power Settings
  5. Scroll down to Display
  6. Select "Enable Adaptive Brightness"
  7. Switch both selections to "OFF"

Thank you for your reply. Prior to posting the question I had checked these settings and both selections were off.

I do not know why, but the issue has abated. I had not changed any settings as I awaited a reply to my post, but the dimming has stopped.
