The failure of autofill could be due to a number of reasons:
-
URL and/or URI match detection method needs to be adjusted.
-
Linked custom fields may be required.
-
The website HTML/JavaScript for the login page may include some idiosyncrasies that make the website incompatible with autofilling.
-
There may be interference from other browser extensions, or from the browser’s native password manager/autofill functionality.
Thus, this type of problem cannot be diagnosed unless you let us know the URL of the website you are having problems with.
