 The Application panel is a Firefox Developer Tools panel meant to allow the inspection and debugging of features usually present in Progressive Web Apps, such as service workers or the Web App Manifest.
 
-### How to enable the Application panel
-
-At the moment, the panel is shown by default on Nightly and Dev Edition builds only, behind a configuration flag. In order to enable it, type `about:config` in the address bar, look for the `devtools.application.enabled` flag and set it to true. It will then appear as a tab with the rest of the panels within the Developer Tools toolbox.
