This handy extension from the analytics team at Search Discovery allows you to select environments for Adobe Launch and to toggle the debug and staging mode for Adobe Dynamic Tag Management. The debug mode tells the DTM or Launch library to add application messaging to the console. The staging mode for DTM uses the staging library instead of the production library. For sites using Adobe Launch, the switch allows easy switching of environments within a property.
Once installed, an icon will appear in the address bar when a site has Adobe Launch or DTM installed. Click on the icon to expose the control panel.
