Google SSO Not Working On Firefox

Hello,

Whenever I attempt using Google's SSO to access any web service via Firefox, the browser keeps thinking and thinking and does not want to actually log in.

No actual "error" happens; it just seems that Firefox won't actually make a connection or authorize Google SSO to log me in.

I have tried updating the browser to the latest settings, deleting cache/cookies/history/etc., restarting the app, restarting the laptop (MacBook Pro M4), and performing a full system shutdown and re-up. So far, nothing.

Help?
