Everytime I open Mozilla Firefox it shows a lightbox on the screen just saying CONTINUE. I just want know what is that because it wasn't there before and doesn't start to appear after a upgrade, just star all of the sudden. Is that normal, is that a virus, is the OS doing that...? Do I have to worry? What is it? Thanks.
