### Via Bookmarklet

If you are using a browser other than Chrome or Firefox, you can use the
bookmarklet option to use the Inspector.

Add the following bookmark:

<a href="javascript: (function() { var s = document.createElement('script'); s.src = '//ember-extension.s3.amazonaws.com/dist_bookmarklet/load_inspector.js'; document.body.appendChild(s); }());">Bookmark Me</a>

To open the Inspector, click on the new bookmark. Safari blocks popups by default, so you'll need to enable popups before using the bookmarklet.

### Mobile Devices

If you want to run the Inspector on a mobile device,
you can use the [Ember CLI Remote Inspector][ember-cli-remote-inspector] addon.
