@leocg Thanks for the reply. I'm afraid I'm too much of a dummy to manage it without full instructions. I have switched the flag to Enabled, and rebooted the browser. I ran the import from MS Edge again, with only Passwords checked. It confirmed with check mark that it was done. But, I don't see the password list under the Auto Fill settings. How exactly do I execute the import from CSV file?
Edit: Never mind, I found it! The Import menu item is hidden within a drop down (3 dots) next to the Add button.
Btw, I think it will do no harm to the elegance of the interface to have Import and Export buttons. I mean visible by default, not hidden in the drop down.
