I just restarted my macbook, and suddenly firefox's display looks like this. I've tried looking in setting for the option to turn this off but I couldn't find anything which suggested it. If anyone knows could you please help?

This is how tabs like google search and google slides look. And the blanking out in the firefox add ons manager.

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.
