I'm not exactly sure what you're doing here. Do you have something on the server side which should translate to some HTML or JScript on the client side, and it's only happening if you have IE on the client? If this is the case, you can check to see if the server is intentionally not sending it to Firefox clients by changing the useragent string in Firefox. To do this, type "about:config" in the address box and change the "general.useragent.extra.firefox" value to match IE. Sorry, I don't know what it is.
