Why don't I have a Zoom feature using Android TV Box?

No Zoom feature using Android TV Box.

I have a MXIII Android TV Box. I have found that the zoom function (to increase size of web page) is not offered in Chrome or Firefox like it is on my desktop using Windows. I understand that it would not be needed for smart phones and tablets, due to the pinching feature touch screens have, but what can I do to get some kind of zoom function?

Thanks in advance.
