tinyMCE not working in FF

I am trying to run the examples for tinyMCE editors. The examples work in IE and Chrome but do nothing in FF. I get an error in firebug saying the tinymce is not a function. I looked on their support page, don't see anyone else having the issue. I have not altered their code or embedded it into any of my own. Just trying to run their example. You can download it here. I tried the main package and jQuery package both w开发者_如何学Pythonith the same result.

Anyone have any bright ideas ?

looks like Firefox has restrictive access to the local file server. Once I put it on a real web server it worked.
