What's the deal with Sharedobjects and Firefox?

1

test 1 - works fine in IE, Safari etc… not Firefox

// Get the kookie
var my_so:SharedObject = SharedObject.getLocal("kookie", "/");

// Get the user of the kookie and go to the frame number saved for this user.
if (my_so.data.intro != "done") {
    play();
}else{
	gotoAndPlay(90);
}


// call this rememberme function to know the intro has been played
function rememberme() {
    my_so.data.intro="done";
	
}

test 2 - same story only it “works” in Firefox- only for some reason it skips to frame 64 instead of 92

obj_ft = SharedObject.getLocal("runfirstime", "/");

//function setFirst() {
        obj_ft.data.firstime = "run";
        obj_ft.flush();
//}
if (obj_ft.data.firstime != "run") {
        trace("that' s the firtstime we meet!");
        // this will be shown in the first time
} else {
        // this will be shown after refesh
        trace("hey - i know ya");
		gotoAndPlay(92);
}

seriously - I’ve been trying to figure this out for much longer than I wanted to. I have searched here and googled for more info- has no one else run into this?
