If an IP address can be extracted from the hostname portion of a URL, the IP address matching will be performed at onBeforeRequest() time. Regardless, IP address matching will subsequently always be performed at onHeadersReceived() time as the request details at that point contain a reliable IP address value on supported platforms (Firefox- only as of now). The `cap_ipaddress` now evaluates to `true` in Chromium-based browsers. Even though these browsers are unable to provide reliable IP address value at onHeadersReceived() time, they can still perform IP address matching for IP address extracted from hostname portion of a URL.
