As of this morning (7-5-25), the app Firefox and only the Firefox app turns my entire phone screen grayscale when it is open in the foreground. The color transition takes about a second, and if I tab to another app or the home screen it takes about a second to transition back to full color. I cannot find any active grey scale settings in either my phone or the app. I have downloaded no extensions to my knowledge.
