[PM-40668] On Waterfox one gets "Unrecognized browser" on passkey-usage, though Waterfox is in the "FIDO2 privileged browsers list"

[pamperer562580892423]

Steps To Reproduce

1. Install Waterfox on your Android phone
2. In Waterfox, go to community.bitwarden.com
3. There, try to log in with passkey

Expected Result

Passkey login to be successful without any "incidents".

Actual Result

The BW Android app shows the following error message:

And of course I can choose "Trust", but as Waterfox already is in the FIDO2 privileged apps list (see "Additional context"), that error message shouldn't come up in the first place - and it shouldn't be necessary to "Trust" manually.

Screenshots or Videos

No response

Additional Context

I have Waterfox version 1.2.6 installed on my phone now.

From what I understand, Waterfox is already in the "FIDO2 privileged browsers list":

{
      "type": "android",
      "info": {
        "package_name": "net.waterfox.android.release",
        "signatures": [
          {
            "build": "release",
            "cert_fingerprint_sha256": "29:39:99:7A:2D:8F:07:30:3C:EB:37:AD:68:10:AF:EF:0B:DA:71:0B:E2:11:64:76:E3:52:5A:73:79:EC:2E:1A"
          }
        ]
      }

It looks like this entry has to be updated?!

PS: Ah, in retrospect I'm not sure if I had better chosen the "Passkey Bug Report" form/category? 🤔
