Hello! I am working on a web page with a login form whose input elements change their background on focus and if their value is not null they keep that background, otherwise the background is changed when focus is changed. Everything works fine except in Firefox when I confirmed that I want to save the username and password it autocompletes those fields and I don't know which event the password manager triggers since onchange doesn't seem to work. Setting the autocomplete property doesn't seem to help either.
