Does Firefox address autofill fill in inputs that are hidden with CSS? If so, should it?
I ran into an issue today where a honeypot field in a form I created was populated by the Firefox address autofill feature. This was causing a form submission to be rejected for a human user who was trying to register on my website. The field was a normal input element of type "text" but the containing div was hidden with CSS. When I tested the form with Chrome and Edge's address autofill feature it didn't populate it. Is there a reason this behavior is different in Firefox? Does it also fill in inputs of type "hidden?"

Perhaps you're right. You can read some discussions about it under these bug reports:
There are some interesting points made in the first report. "Hidden" is indeed hard to define. However, not filling an input that appears to be hidden seems a lot safer than filling it. If there is a CSS rule to hide an input or its parent element I wish it would just err on the side of caution and not fill it like the other clients seem to.
That is certainly a point one could add to one of the relevant bug reports.
Good idea. Done. This was resolved for me by using a name that's unrelated to address information for my honeypot field.
