Just updated macbook pro to 11.5.2 Big Sur. Firefox is updated to latest version

Now my gmail is in black and white with tabs & buttons ("delete" "mark unread" "archive" etc) not visible. Calendar is in black and white google drive is in black and white

I've tried changing templates back to dark mode which I like using -no change.

In preferences - let websites choose own color is selected.

Gmail/calendar/drive all look normal on Chrome.

A few screenshots attached for examples

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.

  • 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.
