Not on macOS at least, the Firefox user agent on my uptodate M1 MBP says that I'm on "Intel Mac OS X 10.15".

PS: and on my Win11 machine Firefox says that I'm on 'Windows NT 10.0', which AFAIK is the same NT version that was also reported on Win10.

And on Linux it says you're on "X11" even if you're a proud Wayland session user!
