Im using facebook javaSDK for my website and I have a weird problem. When I load the website with "internet explorer" it always runs fine. When I load the website with firefox it always loads TWICE, and when I use chrome the JSDK sometimes loads once and sometimes not loads at all , giving me the error "Uncaught ReferenceError: FB is not defined ". I tried using asynchronous loading for the SDK but still the same problem. btw I have firebug on firefox, could that be the reason the JSDK loads twice? Thanks
