In Bug 183192 I removed general network API access. Unfortunately, the stock "(allow-network-common)" also enabled Network Extension access.
Amusingly, Network Extension is really more about understanding URLs than it is about networking per-se, so it should not have been removed since it is used by our content filtering logic.
This path adds access to the Network Extension features back to the WebContent process so our content filtering features work properly.
