Writing a plugin using NPAPI + D3D. It works on Firefox, but the browser is black. What for?

Question

I am writing a plugin using NPAPI and D3D. I just simply put the D3D sample from DXSDK and NPAPI together. I get HWND when the plugin starts up and I passed it to D3D for drawing.

It works. control (rectangle 400 * 300) on the test page. Shows what I expected.

But all other areas in the FireFox window are black, including the menu bar. The rest of the contents of the test page is not visible.

I tried only InitDevice (D3D) with HWND and am not doing anything at all. But still there was the same problem.

Can someone help me plz here?
