JACK w/ libflashsupport dont work

Hello all,

I'm using JACK for my stuff, and I need the sound of internet and flash videos in order to do my stuff

I've installed libfflashsupport like described here,
http://jackaudio.org/faq/routing_flash.html

all was fine but it dont make anything.The lib is installed

Maybe its a problem with midori
I'm pretty new to the world without firefox, so may be some one may have the solution of my problem

Thank you !
