Downloading the image several times, is it a Firefox or NivoSlider bug?

When I open two tabs using the Nivo Slider in each of them, I noticed that the netbug netbug tab shows several requisites of the same image each time the slide changes. It increases the page size (in mb) and memory usage / allocation for firefox.exe. After some time, my computer became very slow, and the allocation of memory in the task monitor was above 1 GB.

How to replicate it: 1- Open http://nivo.dev7studios.com/ in 2 tabs in firefox (tested in 3.6 ~ 5.0) 2- Open firebug network panel in the second tab 3- reload the second tab

here is the proof

I still cannot find a reason or explanation for this behavior. Maybe firefox frees up some memory along the way so that images load from time to time?
