Firefox on Windows only requests a USB security key for my Meta passkey instead of allowing my iPhone passkey

I use Firefox on Windows to manage Meta Business Suite for my business, Goff Housing Solutions. Facebook, Meta Business Suite and Ads Manager all open normally in Firefox.
The problem occurs when I open the protected Meta Business Portfolio Settings. Meta requires my existing passkey for accounts.meta.com. After I click Continue, Firefox invokes Windows Security, but the only authentication method presented is:
“Security key — Insert your security key into the USB port.”
I have never owned or configured a physical USB security key.
I confirmed that the correct accounts.meta.com passkeys are stored in Apple Passwords on my iPhone. The iPhone can access Meta Business Suite and the protected Business Portfolio Settings normally.
As a control test, I opened the same Meta/Facebook account and the same Goff Housing Solutions Business Portfolio on this same Windows computer using Google Chrome. Chrome opens the protected Business Portfolio Settings successfully.
Therefore, my Meta account, Business Portfolio, permissions, 2FA and existing passkey appear to be working. The problem seems specific to Firefox/Windows passkey handling: Firefox/Windows is treating the authentication request as requiring a physical USB security key rather than offering the existing passkey on my nearby iPhone (for example via QR code/phone authentication).
How can I make Firefox on Windows use my existing accounts.meta.com passkey from my iPhone instead of requesting a physical USB security key?
I do not want to delete/recreate my Meta passkeys, disable 2FA, reset my Meta account, or create a new Business Portfolio because all of those are currently working.
