Firefox is adding scrollbars to the canvas even with the body set to overflow:hidden and the execution of FB.Canvas.setAutoResize();. Every other browser hides the scrollbars. When I remove all content from the page the scrollbars persist.

This is a known issue with canvas apps and page tabs, and has annoyingly been around for quite a while.

Some people mention being able to use
FB.Canvas.setSize({ width: 700, height: 800 });or something likeFB.Canvas.setAutoResize(500);and it gets around the issue.Have you definitely set the iframe auto resize option in the apps control panel too?
