Comment 1 for bug 574113

I completely concur. It has happened to me before with Facebook and Gwibber, and has happened to me twice when now having to re-authorize the Identi.ca account through OAuth. I click the Authorize button, enter my credentials in the Identi.ca website, click Allow, and expect to be done when the Identi.ca screen says done. Considering it done, I click the Close button, completely failing to notice the Cancel and Save buttons you can apparently use.

I think a good solution here would be to immediately save the authorization once a user is authorized, and providing an Undo option, i.e. Unauthorize. If you're going through the complete process of authorizing your account, it's unlikely that this has been done by accident, so you can safely assume that the user will want to save the authorization.
