Describe your environment

Issue noticed in mobile web : Android devices + chrome browser

Operating system: Android 12
Chrome version : 120.0.6099.230
Configuration used : 'signInFlow': 'popup',
Tried different firebase-ui-auth versions 6.1.0, 6.0.0 with firebase JS SDK v9 & v10 compat, but no luck.

In mobile devices Facebook login is not working , No error message/ warnings displayed.
Created exactly same project & updated firebase configurations:- https://fir-ui-demo-84a6c.firebaseapp.com/

Steps to reproduce:

Create exactly same project - https://fir-ui-demo-84a6c.firebaseapp.com/ and try it on chrome browser in an android device
( 'signInFlow': 'popup')
Click facebook login , after login from facebook it will just land on app-login page. without logging in.

Additional information

Working fine in desktop browsers and IOS Devices .
Also noticed, if we changed 'signInFlow': 'redirect', it will work first time , (second time we need to clear the cookie to make it work)

Hi @jobinkurianm, I'll update the Facebook setup for our live demo so I can see if I can reproduce this issue. In the meantime, I wonder if this might be an issue with the underlying Firebase JS SDK - see firebase/firebase-js-sdk#7958 for more info.

@jhuleatt Yes, Looks like issue with firebase SDK itself . Tried direct implementation using 'signInWithPopup',
but getting error 'Firebase: Error (auth/popup-closed-by-user)'

Thanks for confirming. Along with the previous issue I mentioned (firebase/firebase-js-sdk#7958), it's probably worth keeping an eye on this issue too: firebase/firebase-js-sdk#7807.

Having this same issue on our production site. Worse, both signInWithPopup() and signInWithRedirect() are affected in both the 120.x and beta 123.x versions of Chrome, specifically on Android. Literally all other browsers on all other platforms work fine - including Chromium-based browsers on Android such as Adblock Browser.

Is there any solution to this?

did anybody solve this?

Same problem for me, works fine on Desktop and iOS device but not on Android: signInWithPopup returns auth/popup-closed-by-user, signinWithRedirect does not work (getRedirectResult(getAuth()) returns null after redirect).

Hi everyone,

1. Does this issue also occur in other browsers?
2. Could you check if your authDomain matches the domain you're using? If not, please try updating your authDomain to match the domain you're using and see if the flow works.

For example, if your web domain is "example.com",
your authDomain should also be "example.com"

Also ensure that you've add your domain to the list of authorized domains in the Firebase console (Authentication -> Settings).

We're investigating why this is occurring only on Android devices and Facebook provider. Thank you for your patience.

We ended up implementing Facebook native login for the web combined with Firebase manual sigh-in flow (signInWithCredential created with accessToken from fb SDK).

It took some time for Facebook to convince us the login was indeed broken - it worked perfectly fine on desktop, just not on mobile - but somehow they don't provide details like this in the violation reports.
