When I try to autofill a form on Firefox 53.0.3 (64-bit) (Mac), the following message appears:
Cannot Fill Item in Firefox
Firefox is connected but its code signature could not be verified. Filling and other features are disabled until this configuration issue is resolved.
This problem occurs when I try from the full app of the extension.
Autofill worked yesterday.
