My site http://www.zikbay.com/ looks OK in IE7, but there are several problems when displaying it in Firefox:
1) The Search box is not correctly adjusted (comparing to IE7 - ideal)
2) In "Adverise Here" section, the left margin is too big, again this looks fine in IE 7.. I used padding: 10px, otherwise it will not look good in IE 7...
3) In "featured" section. The columns are not equal. The third column is too big. It looks OK in IE7
4) The tabs in Ajax Control "By location", "By Map" - this text is not centered inside of the tab. It looks OK in IE 7
