adblock interferes with an innocent banner

[einsteniano]

Hi, like in title. In firefox 16 the extension interferes (blocking it) with a banner on my site. the banner is on this page http://annaritamaestra.altervista.org/joomla/. The banner is activated by clicking on the + sign. Perhaps this is a feature, not a bug..but the banner is blocked. Other users of the joomla cms reports this behavior of adblock.

I cannot understand Italian, but the banner which is displayed with ABP being disabled seems to be an ad for Red Bull (or for other brands some other times). Am I right?
