Trouble with jQuery and AVG Safe Search plugin for Firefox

Trouble with jQuery and AVG Safe Search plugin for Firefox

Hi guys,
I've some problems with rendering my own web pages using jQuery and jQueryUI (all recent versions) on Firefox (with AVG plugin installed).
Googling for problem solutions I've found some blogs that advise to disable the AVG plugin. But, obviously, I can't ask my users to disable a plugin to see my website!
But... surfing on jquery.com or jqueryui.com everything works fine. There isn't, in any case, any rendering problem. How can it be possible?

Could someone help me, please?
