Firefox Addon: Add options menu to addon icon

Especially during development it’s annoying to reach the options page of a Firefox addon:

1. Hamburger
2. Addons and Themes
3. …
4. Options

There should be a faster way. At least for your own Add-ons you can quite easily add an “Options” menu item to the browser

browser.contextMenus.create({
    title: 'Options',
    contexts: ['browser_action'],
    onclick: () => {
      browser.runtime.openOptionsPage();
    },
  });

Additionally to have to add a new permission to the manifest.json file:

"permissions": ["contextMenus"],

That was easy!
