I tried using Google one-tap sign on on firefox. But, got an error saying:
{"type":"requestFailed","name":"OpenYoloError","message":"requestFailed: The API request failed to resolve: navigator.credentials error: (Missing required 'challenge' member of PublicKeyCredentialRequestOptions.)"}
Does the One-tap feature work in other browsers or is it dependent on the navigation features of Chrome
Firefox is offically supported by the new version of Google One Tap. See details at: https://developers.google.com/identity/one-tap/web/guides/supported-browsers
Firefox block third party cookies by default. So make sure you allow third party cookies for this to work.
I had the same issue, but suddenly figured it out..
This is because there are no Google Accounts in the Browser Credentials. In other words: just log in with a Google Account into Firefox before browsing to the site with Google One Tap...then everything will work as intended.
