I posted a problem yesterday and received an email from Mozilla Support asking me for information. I have NO IDEA how to find my original support problem to add comments - PLEASE let me know HOW to answer the Mozilla Support email (other than this way). Here is what I got in the email: "I can replicate the issue in 105.0.3 and see that it works in Chrome. see screenshot What version of macOS? What version of Firefox are you running?" My answers are: macOS Monterey 12.6 (put on a few days ago - upgrade from Big Sur) 105.0.3 (64 bit) - which is marked "Up to date" So, I have the latest operating system for my MacBook AIr and the latest Firefox Browser and the display issue still exists.
