Is Firefox Android supposed to support third party Password / Passkey managers like Bitwarden?
I tried registering /logging into various websites using my passkeys stored in Bitwarden, but Firefox was always opening the Google password manager.
In the android (15) settings I have selected Bitwarden as the main manager app.
I also tried Firefox beta, same issue there.

I am seeing the same problem using 1Password.
Tested on Android 14 and Android 15, latest version of Play Services, Firefox 138.0.4.
For webauthn.io as well as passkeys.io, I can register and auth with 1Password on Chrome, but Firefox always launches Google Password Manager.

Reporter, could you test this again with Firefox Nightly? I can log in with 1password Credential Manager + Firefox Nightly.

Cannot really speak for 1Password, but at least regarding Bitwarden, this is still an issue, even though i have selected it as my primary password / passkey manager.
