Why is svg not showing up on firefox mobile?

Question

Mozilla Firefox

This svg is not displayed in firefox mobile browsers. What could be the problem? Or maybe there are some options for replacing tags?

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 2554.6667 1066.6667">

      <!-- BG - MAP -->
      <image  class="map__bg" href="img/map/cleanMap.png" />

      <!-- icons -->
      <image class="map__icons" x="680" y="210" href="img/map/icons/icons/icon-1.svg" alt="icon" />
      <image class="map__icons" x="775" y="190" href="img/map/icons/icons/icon-2.svg" alt="icon" />
    </svg>
