Default watch stream in external player

Hello,

I am watching sport streams on bet365 on my android phone and tablet. When I start the stream on my phone I get a popup asking for the application to use for watching the stream and I can select mxplayer for example. On my tablet it will automatically start the stream in the browser. Tablet is a sony xperia tab s with android 4.1.1. The quality with mx player is much better so I would like to know if it is possible to configure my tablet to also display the popup or default to mxplayer. Any help highly appreciated
