netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect") does not works anymore afer ff15.0.1 update ?

more options

since ff 15.0.1 update ( today) netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect") does not ask for the privilege anymore ... Is the xpcom interface outdated ?

Chosen solution

Yes. Starting in Firefox 17 privileged code can not run in a web page anymore. In Firefox 15 you have to manually change a setting to enable it. You can bring that kind of functionality to an extension. Starting points: https://developer.mozilla.org/en-US/docs/Code_snippets/Interaction_between_privileged_and_non-privileged_pages
