Custom 3D-XPCOM component instead of 3D-Plugin ?

Hi !

I have developed a plugin for visualization 3D models. It's based on old
styled NS plugin API. I know there is a new plugin API (in mozilla source),
but no documentation.

My question: Is it possible to displace my plugin by a XPCOM component ? A
component which has the same behavior like plugin ? How I can "embed" a
component inside my webside ? With the <object> tag ?

Or is it generally not possible to use a XPCOM component inside my webside ?

Thanks
