Firefox/Twitter code clash

Firefox/Twitter code clash

I have created a new theme for Rapidweaver and integrated some neat JQuery animated sliding panels and frankly I was feeling pretty chuffed with my efforts as I am far from a JQuery expert.

The site in question is:


In the side panel on the left, I have embedded a Titter feed widget, lifting the code direct from Twitter. In Safari, Chrome, Opera and even jolly old IE this works fine. But Firefox has a fit and displays a blank page  - or just plain won't load. If I remove the Twitter widget the page loads perfectly happily. If I disable Javascript in FF, the page loads (but there is no animation etc) - so there is clearly a JQ/Javascript/Twitter script issue going on here that is causing FF to freak out...

Of course the simple solution is not to add the Twitter feed, but since this is exactly one of the uses I was planning for this sliding panel, that's a fat 'non' option. 

All the JQuery code I have used for the theme has 'no conflict' calls and I have even added specific calls for specific code - so stuff like:

var $j = jQuery.noConflict(); 


and


var $jx = jQuery.noConflict();



The fact that the site works fine in all other browsers makes me hopeful that I have integrated JQ properly, but I am stumped, but this FF problem and needless to say, it has held back some major marketing plans I had for my theme...

Anyone got any clues about this...? 

Thanks for any help.
