When I play single song(I mean it's not an album) and I check the function auto play next song when done. But when the song end the website don't do anything. I use that function on chrome is okay. I love firefox and that function in nhaccuatui.com. Please fix it or give me a guide to use that function. In Vietnamese, auto play next song meaning "Tự động chuyển bài" please go to website "www.nhaccuatui.com", play any song and look in the right you will see it.
