i have recently updated to Firefox V90, and formatting on web sites is degraded. Have lost color, contrast and usability more difficult. No dark mode. Anyone else experience this? I updated to v91 and still a problem.

Chosen solution

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.

Many thanks for the quick response! Changing to "Never" did the trick.
