How can I prevent the online accounts icon from showing in the launcher?
After installing 13.04 and logging in to Gmail in Firefox, I was asked if I wanted to add Gmail to online accounts. I clicked 'yes' and then changed my mind before entering my password. Now whenever I log in to Gmail in Firefox, an online accounts icon shows up in the launcher. If I right click and choose 'quit' then the Gmail tab in Firefox closes. How can I remove this icon permanently, or else disable online accounts entirely?
