TextScroller Autoplay doesn't work after Joomla update (2.5.24 to 3.3.6)

Hye
I have a problem with the autoplay of TextScroller since my website update, Joomla 2.5.24 to 3.3.6, the autoplay doesn't work now. I have read several posts about this same subject in this forum but I can"t solve because Firebug console doesn't display Error code ...
