When browsing sites the browser seems to be white on white. It happened after an auto update. I can't see some boxes or when I check some boxes. Any help would be great.

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"

Try "Never" if the default "Only with High Contrast themes" isn't working.

This can happen if you have set "browser.proton.enabled = false" on the about:config page to disable Proton.
