JQuery Undefined and $ Undefined Errors in Firefox 4
I am doing some work for a client and their version of Firefox 4 is getting JQuery undefined errors, whereas my version of Firefox 4 and every other browser I've tested is fine.  This is when viewing the exact same page!

Does anyone have any thoughts as to why this could happen?  Could it be a caching issue?  Javascript is definitely enabled on the browser.
