I am developing an addon to securely store / retrieve information including user profiles and passwords (an interface to a password manager). It uses a button (or a hotkey) to take information from entry fields and store it.
However this does not work on those sites which choose to popup an “Authentication Required” panel.
If I add a context menu option to do the same thing this also does not work on that panel.
Can anyone think of a way of triggering a function from that panel?
