Please consider supporting Firefox's WebExtensions

Firefox is currently implementing web extensions - these are pretty much the same as the chrome.*, although there are a few differences.

Firefox has created the browser.* namespace which is virtually the same as the chrome.* space. There are two differences:

• browser.* will gain Firefox specific extensions.
• browser.* uses promises rather the callbacks.

@Standard8 hi.

Why you can not use sinon-chrome for FF web-extensions testing?

global.browser = require('sinon-chrome');

before(function() {
  browser.tabs.query.yields([]);
  // or
  browser.tabs.query.returns(Promise.resolve([]));
});

sinon-chrome has supported webextensions api since 2.1.0 version.
