I notice you used height: 100%. Firefox requires that the height of the containing element also be defined when using height: 100%. If the containing element, or any containing element beyond that, has a height of auto, then the height of the image may be undefined and limited to the height of the content. To see whether this could be an issue for your page, open the Page Inspector and check the Layout information for .top (it's among the panels on the right side of the inspector for the selected element).

Okay.

(Hard to guess the problem without seeing the page. If pasting a URL, break the link before .com or other top level domain to avoid delays caused by link moderation.)
