below.

### Bookmarklet

If you are using any 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, just click on the bookmark.

Internet Explorer will open an iframe instead of a popup due to the lack of support for cross-origin messaging.

Safari blocks popups by default, so you'll need to enable popups before
using this option.


### Mobile Development

If you want to run the inspector with apps running on mobile devices,
you can use the [Ember Cli Remote Inspector][ember-cli-remote-inspector] addon.
