Yesterday, I put my laptop in hibernate mode like I always do. When I turned it back on, I was greeted by Microsoft asking me to install Windows 11. Of course, I declined the offer several times. I then noticed that everything I had opened was now closed. So I opened everything up again, including Firefox. My laptop has a wide-gamut display, and colours look oversaturated by default. It's one "feature" of this computer that I don't like. So, anyway, I had to fiddle with the color management settings in Firefox to get page elements like images and text not to look blindingly saturated. Aside from videos still being unchanged, the settings worked great for many months. Now, suddenly after this push for Windows 11, the color management has seemingly gone back to what it was like before I got it looking right. Nothing I change has any effect. Change settings. Restart browser. Nothing. Repeat that process until I'm ready to launch my laptop out the window. I closed out and then re-opened Firefox. I refreshed the browser. I rebooted the system. Nothing. All color management settings don't take any effect.
