• What exactly are you trying to do? It's unclear. Are you detecting from another extension, from a regular webpage? Is this an extension you control? – Xan Commented Nov 27, 2014 at 8:55

Check in another extension:

Check in webpage

https://developer.chrome./extensions/messaging#external-webpage

In manifest file, remember to register webpage you want to check extension from.

"externally_connectable": {
    "matches": ["*://developer.chrome./*"]
}

then you can use chrome.runtime.sendMessage in that page.

If it's undefined then you're missing the management declaration in the manifest:

"permissions": [
          "management"
        ],
