Consistently, calling browser.tabs.query from an extensions’ background page that has the tabs permissions enabled returns an empty array.

Using the following code, with an open extension tabs, returns an empty array:

  url: 'ms-browser-extension://' + + '/*'
}, function() {

    • I can confirm that this is a problem. I think all the details are in the issue description.
      Open an options page in any extension and try running

      browser.tabs.query({url: "ms-browser-extension://*/*"}, tabs => { console.log(tabs); });

      It should return at least one tab, but it returns an empty array.

      Hopefully fixes this.
