We should enable the Application panel on DevEdition when ready.
It's been already enabled on Nightly in bug 1609356

The Application panel is hidden behind this pref:
devtools.application.enabled

It also depends on two more prefs:

• dom.manifest.enabled
  It needs to be true for the Manifest view to work properly. (true on nightly, false on Dev Edition/Beta). Otherwise the manifest view shows a warning message (pointing to the pref explaining it needs to be flipped)

• devtools.debugger.features.windowless-service-workers
  I order to debug or start SW the support needs to be enable (true on Nightly, false on Dev Edition/Beta) The impact is that the user can’t start/stop SW

Harald, the bug 1459962 landed so, it looks like we can enable the Application on 77.
WDYT?

Without bug 1603203, the debug functionality will be broken. Do we hide all the buttons correctly for that case?

I'd be fine with both but am leaning towards having it in Nightly for one more release until we get the UI polish in as well – making sure we get feedback on something that closely resembles the final product. If others feel strongly about enabling it in DevEdition, I could be convinced.

The buttons are disabled if devtools.debugger.features.windowless-service-workers is false.

Ok for me to enable in 78
