Another test I did this morning: this very more simple peace of code
does not work with Firefox 3.0.7 (but works with 3.0.6 & 3.1B2):

w is now the handle of the "MozillaContentWindowClass" class window.

hr=AccessibleObjectFromWindow(tSuivi.w,(DWORD)
OBJID_CLIENT,IID_ISimpleDOMDocument,(void**)&pSimpleDOMDocument);

hr is 0x80004002 with Firefox 3.0.7... :-(
