Steps to reproduce:

Upgrade to Mac OS Big Sur Version 11.5.2

Actual results:

In trying to diagnose the issue with Speed Dial Add ON, I went to about:preferences#privacy

Expected results:

It should look like this page: about:preferences#search
Or this page: about:preferences#home

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I will leave this bug active, because other Firefox-designed pages in this group of pages look fine, BUT, the issue is a result of Apple's latest Mac OS Big Sur update to 11.5.2.

The update turned ON the CONTRAST option in the Accessibility features. The changes that option made to how pages are displayed were many and some sites are programmed to work with that option and others are not.

The result is that an option designed to allow visually impaired people to use a computer led me down a path of filing bug reports with software developers and here on Bugzilla for Firefox that should not be bugs. This one is a bug but not for the reasons stated. The graphic isn't designed to work with the CONTRAST option being on.

This was all Apple's doing. I know for an absolute FACT I did not turn on the CONTRAST feature in Accessibility. Idon't even know what it does. I edit photos on my MacBook Pro and would have noticed last night if something had changed in the display of web pages. These funky display anomalies only appeared after I ran the 11.5.2 update.

This is Apple's bug, no one else's. The most junior engineers at Apple write the installers. And whatever changes in OS 11.5.2 were made (Apple provides no release notes or documentation at all) I am sure leaving my computer with an option checked that I didn't check was not in the original specification for the installer.

Just some engineer's mistake.

I'm going to tentatively close this as a duplicate of bug 1725032.
