I'm having permission problems while loading xml into firefox, also in the same domain but in a different port. So I came across the issue in the subject. Well, my problem at the moment is that running the code found on http://www.mozilla.org/projects/security/components/signed-script-example.html I get always "Permission to read preferences was denied."; Here my example: http://nuthinking.com/permissions.htm Does anyone have an idea why this isn't working? Thanks, chr -- ___________________________________________________________________ { Christian Giordano's site and blog @ http://cgws.nuthinking.com }
