Firefox 91 looks totally different on my Macbook Pro

I have used Firefox for the past 20 years on my Mac Computers and never had a problem until the 91 update from yesterday. I was using version 90 on both computers before. My iMac using system 10.14.2 has no problem with version 91 but my MacBook pro using 10.13.6 is having a major problem. All the pages look totally different than what they used to - like it’s missing color, clear format and it looks blankish. I will post two photos here - the first one is what my email page used to look like and the second one shows what it looks like now. Any and all pages I go to now using Firefox 91 shows the same. Even the weather page lacks color and no more videos in the middle of the page. It is bleak and blank looking. It’s awful.

What can I do to get back how my firefox used to look before downloading version 91 onto my MacBook pro?

Thank you, Martha

Looks like 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.

This photos of the weather channel show it even more so how different they are. The first photo is what it used to look like (taken from firefox 91 on my iMac) and the second is what it looks like now on my macbook Pro.

Thank you so much, cor-el, I am much relieved. :)

Gratefully, Martha
