This one is the closest I can find, but this one does not work in Firefox. Work in IE and Safari, but no in FIrefox.
I'll have to disagree with your generic statement that it doesn't work on FireFox. I wouldn't release something which does not outright work with a specific browser and many people (check our forums) have got it working fine on all browsers. Something specific in your setup has probably resulted in this not working correctly on your website, but dismissing the module completely as not working with FireFox is taking it a bit too far.
