done. thanks jed!
also, you don't need a space between return and !!.
perfect, now is 123 bytes
the replace statement is somewhat big. Without it, you have 3 bytes less:
function(a,b){try{a=new ActiveXObject(a+b+'.'+a+b)}catch(e){a=navigator.plugins[a+' '+b]}return!!a}('Shockwave','Flash')
perfect atk! thanks
