Buttons not showing up in Firefox WebExtension notifications
<p>I am working on a Firefox WebExtension in which I am trying to display a notification with a button. I have this working in Chrome. According to the <a href="https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/notifications/create" rel="nofollow">docs</a>, this is supported in Firefox. Buttons are listed as Optional in the <a href="https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/Notifications/NotificationOptions" rel="nofollow">NotificationOptions</a>.</p>

<pre><code>chrome.notifications.create(notificaitonId, {
        type: "basic",
        iconUrl: chrome.extension.getURL("images/unknown.svg"),
       title: "Blah",
       message: "A Message",
       buttons: [{title: "Get More Details"}]
});
</code></pre>

<p>When I run this code, I see the notification. But, I don't see a button.  Am I missing something? Is it actually not supported? The only <a href="https://github.com/mdn/webextensions-examples/blob/master/notify-link-clicks-i18n/background-script.js" rel="nofollow">example for notifications</a> doesn't use buttons so that hasn't been helpful.</p>
