What sheild settings are enabled? does it work with Sheilds disabled?

I created a test database without issue here, though directions to replicate any issues would help

[ForgotPants]

Yup, I have tried it with Shields disabled as well. It keeps giving the same error.

I was using Firefox before this so when I installed Brave, I migrated all the settings, cookies included, to Brave. Every other Google product (Analytics, Mail etc) works fine except Firebase.

Could you try on a new profile (maybe Brave Nightly?) see if that changes things (without importing any settings over).

[ForgotPants]

So it works in the Nightly version. Something must be wrong with my cookies

[fanboynz]

Could try clearing your cookies/cache and retesting

[ForgotPants]

Well, it works now. Earlier, I searched for terms like google, firebase etc and deleted those cookies. Right now I did a full clear and it works

Clearly something was going wrong with cookie migration.

Thank you for your help!
