On my site, go back button reload multiple time same page - only on firefox!

Hi from Italy, I'm webmaster and i've a problem with firefox and my website on article with google adsense ads. When an user navigate the site with firefox (only browser who do this error), the page seem to multiple loads same time on background, and when the user press back button, firefox reload same page multiple times! This problem seems resolved using ABP plugin, and seem to caused by adsense, But the other browsers not have any problem and the code is official from Google. Website: www. t a r i f f a n d o . it (remove blank space) - navigate the article to see the problem! No ADS on home page = no problem!
