I think your main issue here is that it may not be something that all browsers (or servers even) would allow you to do. Especially if now you tell me it works only in Firefox. I am probably not the person to ask, that seems pretty specific. You don't even need jQuery Easy, just add the jQuery library by hand whenever you need your specific code. I would suggest you look in forums where people talk about this kind of Ajax code, you probably would have a better chance to get answers... I am sorry I do not have a better answer to give you...

Like it is explained in the documentation and the tooltip for the parameter, you can enter a path per line
