This is a feature request (though probably in the wrong spot).

One of our users is having her name autocompleted in Safari. This can be disabled on a per-user level but not (easily) for every user in the site.

This feature I believe would be useful in the system settings.

This is the guide to set this flag per user: https://confluence.atlassian.com/conf54/confluence-user-s-guide/creating-content/using-the-editor/using-autocomplete#UsingAutocomplete-Enablinganddisablingautocomplete
