Fullscreen mode still not taking effect with Firefox 57

Question

Just installed the long awaited Firefox 57 on my Android and am disappointed to see that Fullscreen still does not work :-( even though it was heralded here

"The fullscreen value of the Web App Manifest display field is now supported in Firefox for Android 57 (bug 1126479)."

Has anyone got this working?

Try my Brotkrumen Web App for an example.

Here is my manifest: -

{
  "short_name": "Brotkrumen",
  "name": "Brotkrumen Web App",
  "description": "Native Background Geolocation POC",
  "icons": [
    {
      "src": "gingerbreadhouse.png",
      "sizes": "48x48 128x128 144x144",
      "type": "image/png"
    }
  ],
  "start_url": "TravelManager.html",
  "background_color": "#00ccdd",
  "theme_color": "#00ccdd",
  "display": "fullscreen"
}

According to Bugzilla it will ship in 58. Don't know why it was delayed.

"Oh I see the problem -- that particular bug landed in 57, but PWA are not enabled at all until 58. Hope this clears things up."
