Getting error: "Error: TypeError: netscape.security.PrivilegeManager is undefined", when new tab or window opened
Can Firefox/Mozilla fix this for me, as quickly as possible?

This issue can be caused by an extension that isn't working properly.
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.
I fixed the problem on my desktop running Windows 7 pro and Firefox 18.0.1 by disabling the AVG toolbar extension, restarting Firefox then re enabling the AVG toolbar.
Thanks Cor-el, David+L..deeply appreciated!
I'm no longer having this problem since the Firefox upgrade.
