Hi, it seems all the websites I visit on Firefox don't look right. Here is an example of what YouTube looks like on Firefox: https://i.imgur.com/EcWgbva.png And this is what YouTube looks like on Safari: https://i.imgur.com/tfGVJhb.png I'm using Firefox 91.0 on MacOS 10.12.6 on MacBook Pro (2015)

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.

Make sure you are not blocking content.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Ah ha, I unchecked "Increase Contrast" and that fixed it. Thanks!
