I don’t think you can enable it for specific users – but everyone can manually enable it for himself for a single session:

For one-time session, enable it in console:I18n.verbose_localization_session()From that point on when you reload the page you will get a localization session. Once you close the tab, it will go away.

You can find more information in the rest of this topic.
