For me, everything that your site works in firefox for me, but not in chrome, looking at your code, and this is caused by your naming conventions. Namely #advertise
I use the adguard extension in chrome and below - it is the css that it connects to my html pages to hide ads, so I assume that you are using the ad unit in firefox
#adsense_top, #adsensewide, #adspace, #adspace_top, #adspot-300x250-pos-1, #adspot-300x250-pos-2, #adswidget1-quick-adsense, #adswidget2-quick-adsense, #adtext, #adtop, #adv-masthead, #adv-top, #advert1, #advert2, #advertbox3, #advertise, #advertisement1, #advertisetop, #advertising-container, #advertising_wrapper {
display: none!important;
}
