Cannot use Google sign-in in third-party websites
I recently started experiencing errors for logging into third-party websites that use Google sign-in.
On one site (coches.net), I have the sign-in popup loop for like 3 times and then disappear but leaves me unlogged.
On the other site (etoro.com), the sign-in popup shows but then I get an error message from the site about the login. Then it won't let me reconnect since CloudFlare won't accept my "I'm not a robot" prompt and keeps reloading the same page.
This started happening yesterday. I'm not aware of any Firefox or Anti-Virus updates that have happened since, measures not existing yesterday.
I can sign-in correctly from Chrome with no issues.

Thanks @cor-el, it was indeed the Enhanced Tracking Protection that was blocking the authentication with the site.
