I want to write a user script that runs some custom JS on each <input type="password">
field that gets loaded. I could register an event handler on document load to look for all input fields and run the JS on them, but that means firstly that the JS won't run on input fields that subsequently get added by other JS, and secondly it won't run until the page is fully loaded.
I want to put ChromaHash into all of my password fields.
