Below are some common issues you may encounter when using the Inspector, along with the
necessary steps to solve them. If your issue is not listed below, please submit an
issue to the Inspector's [GitHub repo][ember-inspector-github].

### Ember Application Not Detected

If the Inspector cannot detect an Ember application, you will see
the following message:

<img

Some of the reasons this may happen:

- This is not an Ember application
- You are using an old Ember version ( < 1.0 ).
- You are using a protocol other than http or https. For file:// protocol,
follow [these steps](../installation/#toc_file-protocol).
- The Ember application is inside a sandboxed iframe with no url (if you
  are using JS Bin, follow [these steps](#toc_using-the-inspector-with-js-bin).

### Using the Inspector with JS Bin

Due to the way JS Bin uses iframes, the Inspector doesn't work with edit
mode. To use the Inspector with JS Bin, switch to the "live preview" mode by clicking on
the arrow circled below.

### Application is not Detected Without Reload

If you always have to reload your application after you open the Inspector, that may mean
the application's booted state is corrupt. This happens if you call `advanceReadiness` or
`deferReadiness` after the application has already booted.

### Data Adapter Not Detected

When you click on the Data tab, and see this message:

<img src="/images/guides/ember-inspector/troubleshooting-data-adapter.png" width="350">

It means that the data persistence library you're using does not support the Inspector.
If you are the library's author, [see this section](../data/#toc_building-a-data-custom-adapter) on how to add Inspector support to your library.

### Promises Not Detected

You click on the Promises tab, and see this message:

<img src="/images/guides/ember-inspector/troubleshooting-promises-not-detected.png" width="350">

This happens if you are using a version of Ember < 1.3.

#### Missing Promises

If the Promises tab is working, but there are Promises you can't find,
it's probably because these Promises were created before the
Inspector was activated. To detect Promises the moment the app boots, click on the `Reload` button below:

#### Inspector Version Old on Firefox

Firefox addons need to go through a review process with each update, so the Inspector is usually one version behind.

Unfortunately we don't have control over the Firefox review process, so if you need
the latest Inspector version, download and install it manually from
[GitHub][ember-inspector-github].
