It is possible to disassemble a Firefox XPCOM?

it is possible to res开发者_如何学编程tore (pseudo) code from a Firefox XPCOM DLL? I know there is a Firefox plugin called XPCOMViewer what shows me classes and interfaces and this works fine but I need more to know about what this XPCOM do.

The plugin has a function "Generate Code", anyway nothing happens when I try to do this.

Have you any advice for me how I could do this?

Yes, it's a regular DLL and can be disassembled as any other executable. If you expect to get something more understandable than assembly, then no - XPCOM DLLs are regular DLLs built according to special conventions.
