at http://abest.ru
after loading click on any point at the left menu tree: Brother, Canon, etc.
and then on any of sub items, after right page finishes loading firefox continues using CPU (30-40% at my computer) and process memory slowly but constantly increases.

Reproducible: Always

Steps to Reproduce:
1. visit http://abest.ru
2. click on any Brand name in the menu
3. click on any subitems that appear under opened Brand name
Actual Results:  
firefox continues unexplained CPU usage (no flash plugin on the page, just plain html) and firefox.exe process's memory is huge and growing (i waited till 130Mb), sometimes it is back down but then grows again, eating CPU

Expected Results:  
stop processor usage after page is loaded and act like on every other page (even bigger and more complicated)
