See the url. The problem is with position:relative; of the h4 that firefox ignores, if you see http://www.foldit.org/index2.html firefox renders the same as other browser without position:relative; of the h4. works in ie8 and 9 chrome opera and safari thnks Reproducible: Always Actual Results: the img tag doesn't apply the 100% width on the parent Expected Results: the img tag should apply the 100% width on the parent

Please try it again with Firefox4 beta12 or later. http://www.foldit.org/ looks ok for me with Seamonkey trunk

firefox 4.0b12, still renders incorrectly
