I can get an IAccessible object from a Firefox window using this code:

Guid guid = new Guid(\"{618736E0-3C3D-11CF-810C-00AA00389B71}\");
object obj = null;

Apparently you can't get the full HTML source using IAccessible. I found this but it doesn't work in FF3.5:

IServiceProvider *pServProv = NULL;
pAccessible->QueryInterface(IID_IServiceProvider, (void**)&pServProv);
ISimpleDOMNode *pSimpleDOMNode;
if (pServProv) {
  const GUID refguid = {0x0c539790, 0x12e4, 0x11cf, 0xb6, 0x61,
                        0x00, 0xaa, 0x00, 0x4c, 0xd6, 0xd8};
  HRESULT result = pServProv->QueryService(refguid, IID_ISimpleDOMNode,
                                           (void**)&pSimpleDOMNode);
  if (SUCCEEDED(hresult) && pSimpleDOMNode != NULL) {
    /* This is a Mozilla node! Use special ISimpleDOMNode methods described in
      ISimpleDOMNode.idl. */
  }
}

I also found this, which doesn't work in FF3.5 either:

HRESULT hr = AccessibleObjectFromWindow(hwnd, OBJID_CLIENT,
      IID_IAccessible, (void**)&pAccessible);
if (SUCCEEDED(hr) && pAccessible != NULL) {
HRESULT hr = pAccessible->QueryInterface(
      IID_ISimpleDOMNode, (void**)&pSimpleDOMNode);
}

I'm stuck. :(
