779869 - "ready" tab event is not fired for images

Status: RESOLVED INVALID

(Add-on SDK Graveyard :: General, defect, P3)

Description

[Matteo Ferretti [:zer0] [:matteo]]

If an image is opened in the browser (or with tab's API), the tab's event "ready" is not fired. Here a simple add-on to reproduce it:

  const tabs = require("tabs");

  // Both ready and open are fired
  tabs.open({
    url: "https://www.mozilla.org/",
    onReady: function(tab){
      console.log("ready", tab.title, tab.contentType);
    },
    onOpen: function(tab){
      console.log("open", tab.title, tab.contentType);
    }
  });

  // Only open is fired
  tabs.open({
    url: "https://www.mozilla.org/media/img/home/firefox.png",
    onReady: function(tab){
      console.log("ready", tab.title, tab.contentType);
    },
    onOpen: function(tab){
      console.log("open", tab.title, tab.contentType);
    }
  });

A tab's `pageshow` event was added in bug 671305 since URLs that do not have DOMs don't fire a ready event. Opening another bug for it since `onPageShow` isn't available for tabs however (must be done via tabs.on('pageshow')).

Matteo, can we close this?

Closing this due to pageshow event being added in bug 671305
