+      Note that, for security and privacy reasons, extensions are not allowed to be installed using this policy. Moreover, the devices on the Stable channel will only install the apps that belong to the whitelist bundled into <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph>. Any items that don't conform to these conditions will be ignored.

       Each list item of the policy is a string that contains an extension ID and an "update" URL separated by a semicolon (<ph name="SEMICOLON">;</ph>). The extension ID is the 32-letter string found e.g. on <ph name="CHROME_EXTENSIONS_LINK">chrome://extensions</ph> when in developer mode. The "update" URL should point to an Update Manifest XML document as described at <ph name="LINK_TO_EXTENSION_DOC1">https://developer.chrome.com/extensions/autoupdate</ph>. Note that the "update" URL set in this policy is only used for the initial installation; subsequent updates of the extension employ the update URL indicated in the extension's manifest.
