Firefox can memorize form data with no problem such as an email address. However when I go into a form field, for such items as an email address, I can see a list of email address choices but I can not select one to populate the form field. This was working fin on Firefox v55.0.3. I just upgraded Firefox v68.02 and this problem occurred. NOTE: On another PC that had been on Firefox v55.0.3 and was subsequently upgraded to Firefox v68.02, no problems were noted.
