I’m new to using firebase authentication and I’m using google auth provider for logging into my application. I noticed that if I was signed into a google session (say gmail) in another tab and then sign into my application via google (using a firebase popup) that I would be logged in and routed accordingly. However, if I was logged out of google elsewhere, and then login using firebase/google popup, the login would succeed in the popup window but the URL at the top of the window would flash a redirect to: accounts.youtube.com/accounts/SetSID.

Sometimes there is a long string at the end of this URL that I can’t see the whole thing.

Is this normal? Is it normal for there to be a long string at the end of the URL? If not, where could this redirect info be set in firebase, the firebase NPM module, or elsewhere so I can change it? Just concerned as I’ve seen online posts about hackers potentially abusing this URL in the past.
