Is it a reported problem? Problems that developers are not aware of will never be resolved.

So I understand having spoken to BT help line - not everyome affected apparently.

Hi

What seems to be the problem? How can we help?

When will problem of picking up Firefox email contacts be resolved?

Firefox is a web browser and not a email client. So I take it this is with a webmail site in Firefox and since you mention BT https://www.bt.com/help/email/bt-email-login ?

sorry not to advise earlier but I can use BT Mail via Microsoft Edge picking up my existing contacts but via Firefox I get: "Invalid mail address, must have a domain part"

The BT helpline advised me that this is a known Firefox problem for some of their customers. How do I contact Firefox?
