This looks similar to Bug 1660446. When logging in with Google a redirect is performed humblebundle.com -> hr-humblebundle.firebaseapp.com -> accounts.google.com -> humblebundle.com.
humblebundle.com embeds hr-humblebundle.firebaseapp.com. The login fails because the iframe does not get first party storage access.

I was able to reproduce the issue on Firefox 96.0a1 (2021-11-23) under macOS 11.6.1 by following the STR from Comment 0.

The issue is fixed on Firefox 96.0b4 and Firefox 97.0a1 (2021-12-14). Tests were performed on macOS 11.6.1, Ubuntu 20.04 and Windows 11.

I can confirm this is fixed. Sign in with a Google account was performed regardless of the ETP status.
