Ok, I don't have any idea why Zone Alarm only does this to Firefox, but it does and this is the only way around it that I have been able to find:
Open your Zone Alarm control panel and click on the "Privacy" tab on the left. Then click on the "Main" tab at the top and click any one of the "custom buttons." Look at the current settings under each of the three tabs that you see now and then turn all privacy settings off. Then clear your browser's cache and reload the gallery and it should work now. Once you are done viewing the galleries you should then reset your privacy settings back to their previous levels.
