In google the color choices are gone, and I can't highlight anything. On many websites many colors/graphics are gone. When I try to click in a box, nothing happens. I cannot even get the box below where I say yes to getting email when the question is answered. Twitter is a bunch of boxes and outlines now, and doesn't look at all as Twitter used to look. I have tried turning the Mac on and off. This is a desktop computer.
This could be a problem with High Contrast Mode on Mac.
See "New" in the release notes.
Firefox now automatically enables High Contrast Mode when "Increase Contrast" is checked on MacOS in the Accessibility settings.
Make sure you allow pages to choose their own colors.
- Settings -> General: Fonts & Colors -> Colors: "Override the colors specified by the page with my selections above" => Never
