如何在最新的Firefox中简单地测试XPCOM组件？

Question

In the latest firefox, I found that, when you try to use the following code in web console:

netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

[10:33:00.787] Use of enablePrivilege is deprecated.  
Please use code that runs with the system principal (e.g. an extension) instead.

For the firefox 3.6, I always use this way to simply test some of my XPCOM components, it's very convenient. But in the latest firefox, I found that i cannot be used anymore.

So If currently I have written a C++ XPCOM component, is there a simple way that I can try to test it besides having to write and register another test component ?

Of course, any suggestion is very appreciated.

Binary (C++) XPCOM usage is very heavily discouraged (or to put it more firmly, DEAD DEAD DEAD ) in recent Firefox builds:

• http://starkravingfinkle.org/blog/2011/07/add-ons-binary-components-and-js-ctypes/
• http://hackademix.net/2011/07/14/killing-binary-xpcom-in-add-ons-is-javascript-fit/

MDN specifies alternatives for getting binary XPCOM components, although I don't know if any are an improvement for your scenario:

Formerly binary components should now use js-ctypes:
