Hi,
Thanks this worked for me via Floorp 12.9.2@146.0.2 (64-bit), I have access to my account via passkey and and login in with other devices using this method, but just cant export the vault for safe keeping, there are a few things different i noticed tho. Pop out the extension window as usual and go to “Debugger” tab and the line is 603 for me. everything else is the same.
