Yes chromeToPath is broken for recent versions of Firefox only. Still 
works fine in Mozilla builds.

See jslib bug 7959:

We need to implement a Chrome class or just provide support for opening 
chrome URL's. Once a file is in a jar, it is no longer a "local" file.

It can be done, I just can't think of an *easy* way to do it off the top 
of my head ...

Heres the *long* way to do it:
Example uses [chrome://jslib/content/jslib.xul]

js> var ios = 
js>  var uri = ios.newURI("chrome://jslib/content/jslib.xul",null,null);
jjs> var channel = ios.newChannelFromURI(uri);
jjs> var is = 
js> is.init(channel.open());
js> is.available();
js> is.read(is.available());

I'll file a bug and get this type of functionality in as soon as I can ...
