I have retested this issue on the latest Nightly build 140.0a1 (2025-04-28), and the original problems are no longer reproducible. Autofill now behaves correctly when clearing the form from the Phone field and when triggering autofill from the Address field.

However, I noticed a slight delay (~1 second) before the Address field is populated, particularly after interacting with the form for a short time and then triggering autofill from the Address field.

I am closing this bug as Verified Fixed. Please let me know if you would like me to log a new issue to track the autofill delay.

The delay is actually expected. The re-fill heuristics run 500ms after the autofill action to make sure all value clearing has happened by then.

Since nightly and release are affected, beta will likely be affected too.
