My 2nd Jetpack script, Using Google Bookmarks.

jetpack.statusBar.append({
html: "Bookmark it!",
onReady: function(widget){

$(widget).click(function(){

var url = jetpack.tabs.focused.url;
var doc = jetpack.tabs.focused.contentDocument;
var title = $(doc).find("head title").html();

jetpack.tabs.open("http://www.google.com/bookmarks/mark?op=edit&output=popup&bkmk="+url +"&title="+title);

//TODO: MOVE TO LAST TAB
});
}
});

Today I watched XUL API but don't know how to use it.
