4. Open Ember Inspector

Expected behavior

Ember Inspector working.

@rgaiacs any errors?

Not for me, but the console does have Ember Inspector Active

looks like there are some missing permissions for firefox now. I had the enable it per website now...

[patricklx]

or go to manage extensions and enable it for all sites.

Thanks @patricklx.

Now that you mentioned, Firefox Extension displays a notification alert:

Set the corrections permission solved the issue.

I just set up a new device and still had to configure the permissions in the extension settings. I'm not sure if the issue wasn't resolved by #2517 or if newer versions of Firefox broke it again 🤔.

i confirmed this on Firefox 125.0.2

[patricklx]

looks like Firefox takes this as optional now.
We need to request it manually
