Beta ext in Firefox stopped autocompleting & clicking icon isn't working either

An example website that stopped working, but my username doesn't autocomplete when I focus on the input and the autofill dialog doesn't pop up when I click the 1Password icon. This happens on other websites, I can add them as I come across.
