For Professional Edition organizations, tab visibility is automatically set to Default On. Salesforce Platform One license users, tab visibility is automatically set to Default On.
   If you choose Default On or Default Off, an option is added to the Create New drop-down list in the sidebar so that users with the “Create” permission can quickly create a new record. For example, if the custom object displayed in the custom tab is named Expenses, an Expense option appears in this list.
