Login is not filled in on a bank site, no "save credential to DB" is offered by Kee in Firefox Quantum for UniCreditBank.net

Login is not filled in on a bank site, no “save credential to DB” is offered by Kee in Firefox Quantum for the site https://cz.unicreditbanking.net/disp?embedcontentname=BusinessNet

Is the reason not to fill-in, because the login cell is set to autocomplete=“OFF”? Can I force autocomplete [on], please?

The second page of the login process is requesting a password. And that password is filled in by Kee. The Submit button is greyed out until I switch tabs back and forth. Can there be done any improvement that the filled in password triggers the Submit button, please?
