Lauching firefox with -chrome option in Mac machine make it to hang. We are calling ./firefox - chrome chrome:// URL

Question

We have written a firefox extension to launch a web site from the applicaiton. We are launching the firefox using the command
./firefox -chrome chrome://iolaunch/content/temp.xul.
till 3.6 it used to work fine. but in 4.0 the above command make the firefox to hang.
the content of the xul file look like below.
<?xml version="1.0"?>
<overlay id="iolaunch-overlay"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<script>
var Cc = Components.classes;
var Ci = Components.interfaces;
cookie_manager = Cc["@mozilla.org/cookieService;1"].createInstance(Ci.nsICookieService);
uri = Cc["@mozilla.org/network/io-service;1"].getService(Ci.nsIIOService).newURI('#URL#', 'ISO-8859-1', null);
cookie_manager.setCookieString(uri, null, 'X-Login'+ '='+ '#Info1#' , null);
cookie_manager.setCookieString(uri, null, 'X-Token'+ '='+ '#Info2#' , null);
cookie_manager.setCookieString(uri, null, 'X-Go'+ '='+ '#Info3#' , null);
</script>
</overlay>
can you tell me why this does not work. Infact none of the chrome URL is getting loaded in firefox 4.0.

Answer 1

You need to use file:// as the protocol instead of C:/. The latter may never work (C:\ might).
Where is the main HTML located ?
Easiest if to store the images in a sub folder of the location because you can't go back via ../ beyond that root location for security reasons.
