Firefox fails to load images on this page that are perfectly linked to. Pressing ctrl + F5 does not help, and the images are visible on the page in other browsers. All the banner images under "460 x 60" fail to load.
Can you reproduce the issue in the Firefox safemode ? - https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode The page looks identical for me in IE11 and Firefox35 and Firefox38 Which Firefox version are you using ?
*facepalm* It was caused by adblock... Disabling it on the site fixed it.
