Firebase authentication compatibility?

So my friend and I were struggling with firebase’s google authentication. Basically, the popup would happen and everything seemed to work fine but it wouldn’t sign in. After further investigation it turned out that firebase’s authentication is not compatible with brave browser. I’m going to test it on some other authentication methods but for now all I know is that google authentication is not working. Is this something we could implement?

thanks

Can you re-test with “Allow all Cookies” in Shields?
