title: Progressive web app not showing install button in browser bar
body: <p>I'm attempting to make a <a href="https://en.wikipedia.org/wiki/Progressive_web_applications" rel="noreferrer">PWA</a> and nothing seems to make the install as web app button appear on my site. </p>
  
  <p>The install button looks like the following and it shows in the address bar: </p>
  
  <p><a href="https://i.stack.imgur.com/n023J.png" rel="noreferrer"><img src="https://i.stack.imgur.com/n023J.png" alt="enter image description here"></a></p>
  
  <p>It shows up when I go to a discourse site but not my own. </p>
  
  <p>I have the following in the head:  </p>
  
  <p></p>
  
  <p>My manifest is in the root directory and is named manifest.webmanifest: </p>
  
  <pre><code>{
    "name": "Example 1",
    "short_name": "example1",
    "display": "standalone",
    "start_url": ".",
    "background_color": "#000000",
    "theme_color":"#ffffff",
    "description": "Example web app.",
    "icons": [{
      "src": "https://www.example.com/test/images/icon_512.png",
      "sizes": "512x512",
      "type": "image/png"
    }],
    "share_target": {
      "action":"/new-topic",
      "method":"GET",
      "enctype":"application/x-www-form-urlencoded",
      "params": {
        "title":"title",
        "text":"body"}
    }
  }
  </code></pre>
  
  <p>There are no errors in the console now. At first there was an error saying it couldn't find the logo image. Once that path was correct the error went away but still no install button. </p>
  
  <p>An example of a PWA is discourse.org forums <a href="https://meta.discourse.org/" rel="noreferrer">here</a>. This site installs fine. </p>
  
  <p>Tested in Brave / Firefox / OS X</p>
