Bug 847168 - [User Story] Email Signature

This console.log should be removed.  I'm guessing this was just debug that got accidentally left in, but if you were thinking it'd be useful long-term then we should probably discuss since its arguably in the realm of private user data we don't want in a log we may solicit for uploading to bugzilla.  (It could identify the user's employer, strongly held beliefs, etc.)
