Add metrics on prefilled values in username fields |
||
Issue descriptionWe should add UKMs to detect websites which prefill values into username fields. We can then analyse this information to split the set into prefilled usernames and prefilled placeholders and use the two datasets to evaluate classifiers on the autofill crowdsourcing server.

This is currently blocked by the fact that an unidentified Chrome component is prefilling values into any password forms. This is going to pollute our metrics and defeat our goal of singling out websites which prefill values. Reproduction: (1) Have a credential saved for https://rsolomakhin.github.io/autofill/ (2) Visit https://rsolomakhin.github.io/autofill/. The credential is autofilled into the password form. (3) Type a unique value into the username field. (4) Navigate to facebook.com. (5) Press the back button. (6) Observe: The unique value is prefilled. The saved credentials are not autofilled. This behaviour is probably desired, particularly on signup forms, but we need to make Password Manager aware of it. |
