1Password Firefox Extension Can't Handle Cross-site Passkeys

On Firefox, when visiting a website (i.e. shop.app) and signing in with the passkey method, it requests a passkey from another website (i.e. shopify.com). When accepting this and following the prompts, WIndows throws an error. Screenshots below.

 

The 1Password extension prompt does not pop up asking to be used, unlike what I’m used to seeing on other websites. I do have 1Password autofill for passkeys enabled in the extension.

 

1Password for Windows 8.12.30 (81230021)

1Password for Firefox 8.12.30.21

Windows 11 25H2

    Hello ​@puppydaze! 👋

    I’m sorry that your passkey isn’t working on shop.app in Firefox. So that we can investigate this further, could you reproduce the issue using the latest versions of both 1Password and Firefox and then I'd like to ask you to create and share a 1Password diagnostics report from your Windows PC:

    Send a diagnostics report (Windows)

    Attach the diagnostics to an email message addressed to support@1password.com

    With your email please include:

    You should receive an automated reply from our BitBot assistant with a Support ID number.  Please post that number here.  Thanks very much!

    -Dave
