To enable the toolbar:
If the toolbar was already enabled, try disabling and then enabling the toolbar again.
You must stay signed into Facebook, Twitter™, or Google+ for Privacy Scanner to work. How you do that depends on the website. You also must not close the tab that the Privacy Scanner automatically opens.
If you close the browser tab opened by the Privacy Scanner before it has finished making changes, then it cannot change your privacy settings.

You have created a Google+ profile, and not just a Google account.
Your computer can connect to the Internet.
