I have a SilverLight application which throws a security exception when running on FireFox

  • 0

I have a SilverLight application which throws a security exception when running on FireFox for Macs. The exact same application works fine on Windows (Internet Explorer, FireFox, Chrome, Opera) and on Safari for Macs.

I am using the Facebook Developer Toolkit available on Codeplex.

The exception is thrown when the user launches the App. At that time I use the SilverLight Facebook API to run some queries using:

facebookAPI.Fql.MultiqueryAsync(queries, QueryAppUsersCompleted, dispatcher);

In my callback function QueryAppUsersCompleted, the FacebookException does not evaluate to null, and its innerException property has a SecurityException in it.

Any help would be tremendously appreciated.
