Block "Would you like to remember this password ?" popup in firefox

Question

i am creating a firefox addon using sdk and i would like to know if there is any way to block the "Would you like to remember this password ?" popup shown by firefox password manager when logging into a website. I have tried "autocomplete" attribute but it looks like firefox has stopped supporting it from version 30. It should not show up while logging in to a website. Please advice.

Answer 1

Add popupshowing event listener and if it's the id of the password baloon, do event.preventDefault(); event.stopPropagation() to stop it's showing.

Or you can specifically target the baloon, by getting the id of it then attaching it like this:

For example:

var win = Services.wm.getMostRecentWindow('navigator:browser');
var PUI = win.document.getElementById('i dont know the id');

var previt = function(e) {
  e.preventDefault();
}
PUI.addEventListener('popupshowing', previt, false);

This code attaches just to the most recent navigator browser window, you will want to iterate through all navigator browser windows, and also listen and attach to newly opened navigator:browser windows.
