I'm looking at the User-Agent strings from MacOS systems running the lastest versions of MacOS 11, 12 or 13. They appear to be reporting they are running MacOS X 10.15.7 Since all versions of MacOS X 10.* are now well past EOL, this causes problems when using this at least do some minimal testing against the system being "supported". Yes, I know it's easy to forge your UA strings, but most people do not, and it at least provides a reasonable base line of what to expect from users.

In what way is the OS version important to you and not the Firefox version ? For browser support, best is to test via JavaScript whether the browser supports specific features.
