When i want to download an mp4 off the Web, before, i only had a pop up which let's me choose system or download and i usually click on download and all's fine. Now, all of a sudden, the pop up has Internet, chrome and MX Player (which i downloaded). I clicked on Internet n another window pops up again with the same options and again i click on Internet n only then the pop up for system or download comes up. What gives??
