Postbank.de does not detect Firefox OS devices as smartphones. The detection is done in this JavaScript file:
https://www.postbank.de/privatkunden/data/mob_red.js
This file is from the mobileesp.com detection framework. Unfortunately, the file is too old to detect all newer smartphones correctly - it contains this comment:

It seems postbank.de has added some code to this file, starting here:

var mobileURL = "https://m.postbank.de/portal/";
var mobileSwitch = function(overrideMobileURL) {

If upgrading, this code must probably be copied over to the new file or otherwise preserved.

If postbank.de upgrades to a version of this script where DetectTierIphone() returns true in Firefox OS, the current code will work. However, detecting devices by name is a fragile approach and will probably require maintenance also in the future. We suggest using this mobile framework more for statistics and add a more robust method to support the site's functionality. The mobile site can be offered through for example any of the following methods:

* screen size detection

* CSS media queries 

* rewriting the site to adapt to any screen automatically

Closing as we are not working on Firefox OS anymore.
