integrating venkman in MFCEmbeded

hello

I am using MFCEmbed application (comes with mozilla build in this location 
"\mozilla\embedding\tests\mfcembed" ) to show some xul pages.
I want to install the venkman.

I build mozilla env with enable-extensions=all
installed venkamn XPI 
http://www.hacksrus.com/~ginda/venkman/venkman-0.9.85.xpi

My question is
after install, how can I call the js to start? its not in the menu (cause 
the mfc embed is not like the fire fox)

typing  x-jsd:debugger in the URL bar is not working (also not working in 
fire fox)

is there a way to make the venkman to work under this application ?

thanks

ady
