Check address dialogue occasionally wont disappear even if you click "OK" or "Abort"
After entering address data in a contact and leaving the address field the
check address dialogue pops up - but occasionally it wont disappear even if you click “OK” or “Abort”.

Firefox 57.0.1 @ Windows 10 Pro
ont disappear even if you click “OK” or “Abort”.
