session handling in Mozilla

Dear Friends,

I have created one bookmarking app.

Bookmark is created using javascript and its a frame.

Its not like a opening a new window like google bookmark.

The problem is when i login from one tab and wants to bookmark any web site from some other tab. It asks me for login in mozilla ff. It should not ask me this.

It works properly in IE when its live and works on local server on mozilla ff and IE too.

I dont get why its not getting the value of session when i use Mozilla FF.

Thanks, Manohar
