The latest update of Diigo Firefox extension 4.1.0.28 shows a Diiigo Library panel on the right hand side of the google search result list. It occupied too much visible estate of my browser content window.
Could anybody provide pointers or instructions on how to disable the showing of the Diigo library panel?

Thanks for the direction. It usually works. But when I am behide a firewall, the arrow on top right corner is not clickable and the spinning image does not disappear.
