Add on needed for work, produces javascript error


My girlfriend is using an app she needs for work. It should generate a javascript window, but before it opens it it says Javascript Application TypeError: netscape.security.PrivilegeManager is undefined Then the window that opens doesn't allow me to populate the fields in it.

Is there any way to get around this?

Whatever add-on this is simply needs to be updated to support new versions of Firefox. Please contact the developer.

Support for enablePrivilege has been removed in Firefox (Bug 546848), so it is no longer possible to get special elevated privileges via the netscape.security.PrivilegeManager interface.

Extensions do not need to use this (they already run code with proper privileges) and if web page use this then they will have to use other ways get what they want like providing a Firefox extension.
