[SOLVED] Can't login using firefox

Hi
I am busy trying to get community builder to work on a new J4 site, when trying to login to the front of the website using Firefox I get the following message, followed by a system generated email.
"Your sign up process is not yet complete! Please check again your email for further instructions that have just been resent. If you don't find the email, check your spam-box. Make sure that your email account options are not set to immediately delete spam. If that was the case, just try logging in again to receive a new instructions email."

When I try to login to the exact same account using Chrome it logs in no issue.
What could be causing this?

I don't see how that could possibly be browser based. That error is entirely server side and it's displayed when trying to login with an account that hasn't confirmed their email address.

I figured it out I was importing data from our J3 site to this J4 test site and needed to not only import the users into the users table but also the profiler table
