I recently installed Firefox 29.0.1 on an XP system, and have carefully reviewed all the settings. I've downloaded a few personas. It seems to render all web sites appropriately. However, I'm concerned that I may be missing something - the footer. The documentation on creating personas shows that they consist of a header image, and a thin footer image. I have a persona applied at the moment, but see only its header, and not its footer. I get the same result if I switch to the default blue theme. It does not matter whether or not the window is maximized. The scrollable area of any website extends to the bottom of my screen if maximized, or otherwise to the bottom of the window's scrollable area.

My main concern is not aesthetics, but that I may be lacking some functionality. I saw an example of a footer image on the page that documents the creation of personas. The footer shown in the image has a small fox icon with a dropdown arrow at one end, and an "x" near the other. I presume that the icon and arrow might provide some kind of functionality, and/or that useful information might sometimes be displayed in the footer. Can you tell me if I should be seeing a footer, and if so, what might be preventing its display?
