When I change the brightness of my computer while Firefox is open, the changes are not saved when I close Firefox. For example, if I lower my brightness from 100 to 80 while Firefox is open, once I close Firefox, the brightness of my screen increases back to 100 after a few seconds. Similarly, when I reopen Firefox, my brightness drops from 100 to 80 as that was the setting the brightness was set at when Firefox was closed. This does not happen with any other program, especially other browsers, that I have on my computer. Do any of you experience or know of this problem and do you have any advice on how to fix the issue?

(I have tried booting Firefox in Troubleshooting Mode, refreshing Firefox and reinstalling Firefox. My computer is also up to date on the latest Windows updates. This issue was not always present with Firefox and only began recently, within the last two weeks.)

This could be about the new prefers-contrast media query.

Reading is now easier with the prefers-contrast media query, which allows sites to detect if the user has requested that web content is presented with a higher (or lower) contrast.

I've changed the settings for Colors in Firefox such that no override of colors is used for high-contrast themes, or at all. So far, it has not affected the saving of brightness in any way.

Are you using Dedicate GPU or On-Board GPU? Sounds like a Video driver issue.

I'm using a dedicated GPU, I believe. It's an NVidia GeForce RTX 3060.
