Unable to view content script references in the developer tools window

Solution
As long as you are on a page that matches the "Match patterns and globs" from your manifest, you will see the content script(s) under the Sources -> Content Scripts pane. You may need to refresh (F5) the page (and/or your extension, then the page) to see it:

Problem
When I view my extension with the developer tools, I only see the generated background file, background.js; my content script doesn't appear under the content scripts tab. Any ideas why? The relevant part of the manifest looks like this: ``` "content_scripts": [{ "run_at": "document_end", "js": ["postMsg.js"], "matches": ["https://groups.google.com/forum/*"] }], ``` postMsg.js gets injected into the page, but never appears in the developer tool window, so I'm unable to debug it.
