Hi.

After the recent update of MacOS Big Sur to 11.5.2, my Firefox browser cannot display web pages in dark mode. I've tried reinstalling Firefox, reinstalling MacOSX, used Time Machine, changed Mac display settings, changed Firefox settings and nothing works. I've attached a screenshot of how my monitor looks after the update. The background is always white If anybody has a suggestion of how to fix this or what is wrong, please let me know so others can benefit from it if they have the same problem.

Notice the white background behind the number 1,2,3,4.

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.
