This sounds like a popover (not sure what the Firefox term is), but I have only ever seen it in response to an action.

As others have mentioned, there are definitely pages that are opened by default on browser starts/restarts, along with tab modal dialogs (also on restart). But yeah - I can't recall seeing a popover featuring Pocket that just happened by itself.
